The breasts aren't that visible.
As it comes to backgroung it fits well the character.
As I'm already making suggestions, for the next time you could make wings in more appropriate proportions, I know it's fantasy art, but that's just the way I am, I'm a percectionist, I like even fantasy creatured to be designed "properly", wings as big to be able to raise the body in air, etc.
But don't take it too seriously, It doesn't prevent me from liking artworks.
