here's what you should do to make it not seems so boring (and seem different). Go into Photoshop (or pain.net a Free program, which is also a photo editor) and go to effects and add noise. This will definitely make it different. I am not saying your skin is bad, it may just be that the program they use (which is likely that they use a program) recognized the steve head and all that black and thought you copied it.
Hoped that helped you.
