Here is my finished painting (watercolor and gouache on hot pressed smooth paper, 14"x20"):
Sorry for the poor quality photo. I took all these pictures with my phone and thought they came out fine. Only when I uploaded them to my computer did I realize some were blurry, and by that time I had already given the painting to my neighbor. :-( It looks much better in real life, I think. But anyway, here is how I got there:
I had first masked out all the trees and the moon with masking fluid and then painted the sky, using cobalt blue, ultramarine blue and permanent rose (I think those were the colors...). Once I was happy with the sky I started painting the background trees by basically scrubbing some shades of brown and purple into the background and blending it a little at the edge where trees meet sky. I removed some masking fluid to paint in the larger trees and started painting some of the darks in the barn.
I started working more on the barn using burnt umber, burnt sienna, sepia and ultramarine blue.
Putting the fence in using similar colors to the barn, burnt umber, sepia and ultramarine blue.
Working more on the trees...
Pretty much finished with the trees and the fence behind the barn.
Finished the trees and put all the snow on the branches, same for the fence and painted the snow on the ground (hard to see, I know, it's snow, but in person it looks better haha). All that was left was the shrubs and plants in front of the fence, and we're done!
And there again is the finished painting.
Hope you like it!
