Here's one I did a few weeks ago in the landscape class I'm taking. The assignment was to paint something with hills and trees, and I was in the mood for something with lots of atmosphere. I'd taken some photos in a rare fog back in July at a park near my house. The instructor really liked it and suggested I could still soften some edges on the farthest line of trees, and I agree.
I'm terrible at coming up with good titles for my paintings, and this is another boring title. If anyone wants to suggest another one, please post it in the comments!
