Here are my submissions and reference photos. I used a 3/4 inch flat brush with gouache on illustration board. I had so much fun exploring the challenge and our recent snowy landscape:) Love seeing everyone's wonderful paintings. Thank you so much!

Bob Ross! I need to learn how to hide secret bushes better, they be too conspicuous in my work Failing that, Richard Schmid for painting and Nicolas Weis for design

Here's me final 5. Done using gouache and tears, first two were plein air, the other three were done at home. The reference photos were taken by myself in and around Edinburgh.  This was a really fun challenge, I've never gotten gouache in so many places that aren't a canvas. I found it quite tricky to simplify the structure way whilst still maintaining readability, but I'm glad its something I'm now a bit more cognisant of. Thanks to Tiffanie for hosting this and doing it along with us and to Prokes too! :) 

Hey there to all! Here is my final submission. Weapon of choice: traditionals Bullets: white/yelow ochre/lemon yelow/ultramarine/burnt umber. Thanks a lot to Proko team and Tiffany for this idea, it was very inspiring to go through Tiffany's vids and fun to try this technique. Martin

super stoked about this challenge, here's my first, incredibly clumsy attempt. Done on a walk along a coastline in Edinburgh. Used gouache and a 1/4" flat brush.
