Vector is nice :)
cant say the same about the wall though
theres too much of a free space, and i DO mean free, composition is not well thought-out
the guy should have took more space
the background looks flat and... whats the ooposite word for deep ^_^'
all the objects have little shades, which actually creates the flatness, and a blurred-vector look
those vivid spots in the sky stand out too much, if you wanted to focus on the character and blur the rest, you shouldnt have skipped them
and the birds look like some random shapes, they dont have to be detailed but the silhouette should be clearer
all in all, not one of your bests
