this is very, very nice! I really love the warm fall colors that you used here. <3 <3 <3 <3 the colors just blend in so well with each other! :D onto some other elements in your wall, i'm quite disturbed by the swept lines that you put into the clouds. D: i mean, it doesn't look so clear if the clouds are supposed to be fluffy (since i can see some underneath the swept lines), or are they supposed to be swept at all. my other point would be the sea. as much as i love the strokes and colors that you used, it looks a bit flat in the distance. D: maybe, putting in some faint waves would do the trick? :D
other than that, this is a very lovely wall. ^^v
