This is amazing!! sooo pretty and the 'weird ass Pocahontas' that's going on looks like it was meant to be there. You really have done an awesome job
Your gonna have to do a tut on your hair for me (just a bit jealous I am!!).
The only things I can possibly critique on this wonderful image would be-
I think adding a bit of a shadow on the far side of the tree, closest to horse, would be advantages as with maybe going through with a burn tool and lightening the far side of the leaves that are flying above her back and chest where the sun would be hitting them. Burning the opposite side of a few leaves would also help give em a bit more depth.
All in all, you have done a brilliant job Amy
(I've sent you a note re. a possible art trade/collab?)
