Such a beautiful scenic wall! The reconstruction on the background scan is seamless, and I like the pink/green color scheme. The only thing I dislike is the brightness, it's too high and Miku looks almost entirely white (no details are visible on her dress aside from interrupted lines). Since this is supposed to take place during sunset, it shouldn't be that bright (like she's facing the midday sun).
The composition's good though, got nothing to complain about that :)
