What the.. Its just a photo-edit?
It looks like an awesome waste of time

The texture job is alright, nice and smoothly placed, but it looks like the only hard part was cutting each peice out properly. From there it was just paste texture > set to overlay/soft light > lower opacity > maybe even add a couple adjustment layers.
And no offense, but the skin looks more like a giraff's than camo.
I think you should do some real skinning

You'd be good at it. Photo edits won't get you far
