I like the idea of this. There's a few spots that I think could be improved, and I think it'd be better to avoid the few times that diagonal lines slip in, but it's a pretty scene.
For the preview thumbnail it's best to crop the full image down to 100x100 or less instead of shrinking it, because that makes it get blurry.
thanks for the critisicm! this was just a little doodlish thing i was doing in the library when i should have been doing something else :3
i hope i get more time to upload something better.
