Bloody as always, but with her guesture and expression, they really convey the feelings you described. Very nice dynamic angle, composition and background. I really like it, after all, it's about an angel. I am an angel / fairy lover or i must say, girls with wings :D
anyways, here are some of the critiques i have:
I don't really understand what those 2 blobs of puffy clouds are for (center top and bottom right). I think it will
look just as nice without them.
Also, I think if you can align the planet at the background with the cloud's horizon line, it should fit in more
with the overall image. Like right now the planet's line is pretty much vertical, if u can tilt it 45 degrees to
fit with the horizon, it should look better. Try that out.
and to more technical side of the critique:
her left wing's editing looks abit rough, i know you can do a better job at it. If you are trying to create a
fading away feel, you should try applying a layer mask with grayscale gradient on the angel's layer. That way, you
can get a very nice clean fade away and it doesn't take up a lot of time. Lastly, I am just being very nit picky,
remove one of the blood dots on her left wing, right now the blood around that area looks repeatative because of the
dots.
(sorry for such a long post and hope that my critiques make sense and helps XD )
