Sky's Just Chilling

:: This is currently a work in progress because I'm not happy with the background ::

I made this with the painting program SAI.

This is my OC Sky who is a bird-spirit, she's chilling out with one of her pigeon companions. She has her wings retracted while she sits.

I'd love to get some feedback on this, since I'm working on a updated version with a more complex background. Please let me know what I could improve Thanks!
