air this is a wall that i made, I don`t know if it good, so please help me to know if it need more changes

beware, criticism ahead
--the 2 birds in the right are way too... identical.
--there are 2 strands of hair that aren't connected to the head at all - a small one in the left edge, and another small one just below the ribbon near the upper edge
--the girl looks more like a giant in the clouds, not like an aerial wannabe

otherwise, it's clean, sharp and nice
