I have a friend on Caedes that uses only Paint.net. I might have to point her in your direction. You are the master of Paint.net as nearly as I can tell. Your range of subjects and styles astonishes me. I don't particularly care for the subject matter, but you've created an interesting parallel universe.
Great work in creating the sun and reflections on the still water. To me it is a tad dark on the outer edges, but just an opinion here. You do creat wonders.
I like the depth and silhouettes in this scene, Rob. I would say soften the shadows up a bit and maybe get rid of that bit of blue in the distance. Interesting work.
