Course Description

Course Description:

In landscape painting the sky sets the mood for the entire painting and is arguably the most important element to get right. And the easiest to get wrong!

In this intensive 4-hour workshop, I will discuss and demonstrate cloudless skies (surprisingly difficult), cloudy days, stormy skies, and sunsets. Watch the demonstrations and paint along or later if you prefer. Then submit your work in the chat for a critique.

Feel free to use your preferred materials. I’ll also provide a supply list if you need guidance and recommendations. This workshop suits aspiring and emerging painters best, but you must have some painting experience.


  • TECHNIQUES for painting cloudless skies with depth and interest.
  • Capturing the DYNAMIC energy of cloudy and stormy days.
  • Creating CAPTIVATING sunsets with vibrant colors and gradients.
  • How to CHOOSE the right sky to complement your landscape and set the desired mood.

Instructor Bio

Deborah Tilby is a Canadian painter currently living in Victoria BC.  She is recognized as one of the top oil painters in the country and is a senior signature member of the Federation of Canadian Artists and has been awarded the status of Oil Painters of America Master.  Her work has won many international awards, has appeared in Fine Art Connoisseur, International Artist, Southwest Art, Arabella and Artist magazines and is in collections all over North America and Europe.

“Painting began for me with my first watercolour at age eighteen. I love watercolour and it held my interest for many years, before I began working with oils. I am Canadian but for fourteen years, England was home and European street scenes and landscapes were my subject. A move to the west coast of British Columbia turned my attention toward the beaches, boats, waves, and marinas of coastal living. Not entirely committed to trading Europe for Canada, I have travelled between the two, keeping my perspective fresh and allowing my work to straddle both continents. I now stick to oils most of the time, only occasionally reaching for my watercolours. I still love watercolour but am drawn to the flexibility, freedom, and richness that oils offer. 

I became a painter by way of being an observer – I have always noticed light and shadow, shapes, texture, composition and colour, and endeavouring to interpret my observations through painting has been a lifelong passion. That people choose my work to hang in witness of their lives is a bonus, both wonderful and humbling.

How many registrations are required for a course to start?

A minimum of 6 registrations are required.  If 6 registrations are not received by the time the course is 24 hours from starting, the course will be cancelled and all registrants will receive complete refunds.

What is the maximum number of people in a course?

This varies for each course.  The maximum number of registrations is decided by the instructor.

Can I get a refund?

Up until 72 hours before a course’s first session you can receive a complete refund. You can cancel your registration via the My Account portal, or by contacting [email protected].

After this time no refunds will be given (if you have extenuating circumstances you believe justify a refund, contact us at [email protected]).

Can I register for a course already in progress?

No. Once a course has started, no new registrations are accepted.

Where will my course be held?

All courses meet online over Zoom. You will need a device equipped with a camera and a microphone to fully participate. 

If you have not used Zoom before, learn about how to use it here.

If you don’t regularly use Zoom, we recommend you join your first session 10-15 minutes early in case your computer needs to install or update Zoom.

How do I join my course?

You will receive a welcome email from [email protected] when you register.  This email includes the Zoom link to join your course session.  You will also receive 24 hour and 2 hour reminder emails before each session, and each of these emails includes the Zoom link.  You can also access the Zoom link to join your course in your MastriusChat group.

Are the sessions recorded?

Yes, every session is recorded and are typically available 24 hours after a session ends.  All session recordings will remain available for the duration of the course, and for one month following the last session.  The recordings are viewable within the MastriusChat platform, and cannot be downloaded.

What if I miss a session?

You’ll be able to watch the session’s recording.  If you have questions the recording doesn’t address, you can ask them in the chat feed of your course’s private MastriusChat group.

What is MastriusChat?

MastriusChat is an online discussion platform.  You and your fellow course registrants will be assigned to a private MastriusChat group where you can connect and support eachother via the chat “feed”. Your group is also where you’ll access the session recordings. Other resources in your MastriusChat group include a link to join your course sessions, and a library your instructor can use to share resources.

What is a Navigator?

A Navigator is an artist who joins your course to ensure both instructor and registrants have an enjoyable experience. They support (as required) with technology, timekeeping, moderating questions, and between-session discussions on MastriusChat. The Navigator has also joined the course as participant, and just like you, they’re wanting to grow their skills and learn the material.

I’m not ready to register because I still have questions. Who do I contact?

We’d be happy to help! 

Reach out to us at [email protected] and we’ll do our best to support you.
