I will also take customs if you want however it MUST be one of your own pictures (for copywrite reasons) I can find background stock and such but again, the picture of the horse must be your own picture :)
7, 9 and 10 are really good. They blend VERY good. You need to work a little on that. Matching the background to the horse....by that I mean the contrast, brightness and colors. Compare for instance 1 and 7.
I was going to manip this one tonight but my software keeps closing on me. Can you do it for me?
