Behind the wolf I see a lot of gradient use or something along those lines that aren't really...I don't know, I feel you can easily do more with the back. The wolf is awesome nonetheless, it blends really nicely with the whole image. The text however...you need to make it easier to read and remove the funny white stuff.
Play around, play around. Use layer effects if you can. You don't really need a tutorial, just experiment with every feature and remember what each does.
