Wow.. you're a really talented artist.
That wing is beautiful
I don't know why but for a moment there I visioned the wing with a little tear off to the side. And you can see a bruised but healthy heart thudding away behind that hole. Not sure that any of that made sense at all. But I just thought that adding an element like that (or any other symbol, actually) would emphasise just how far you've come.
Then again, I'm not a good artist so my opinions on art tend to be a little warped (albeit a little morbid).. and I just realised that that may not be the kind of overall image you are going for
Sorry. But, that's just amazing
