If you want to learn more than the basic PS functions then I suggest you get some of the free actions out there and learn what and how they do things. When I edit my pictures normally I often use techniques discovered by taking apart an action.
I think this version of Stasia with angel wings is the best I have done, in part because I went back to the old PSD file which had all the adjustment layers intact and corrected a few errors that I had made when I first took the shot.
Gorgeous model and image!! Awesome body! Great setting, lighting and blurring. Great addition of the wings. Looks pretty realistic. The only thing I'd say is you shouldn't mirror image the wings making them perfectly symmetrical because that doesn't happen in nature. Just some subtle variations in the feathers will make it even more realistic.
Way better than the skinny Victoria secret angels!!
