Some parts of the spartan's head just makes it look weird and out of shape. I like the bg color, but you could have chose a different render for the sig. I personally don't like your font choice. Make the text blend with the bg more.
Can you send me some links to your fonts? i like them, and for the sig, it looks pretty good, it might be a bit to cluttered by the focal with the splatters and ****.
What's a clipping mask? I need to learn some new techniques and stuff. Around the top of his head where it is blurred, it makes the spartan's head look distorted and weird. Nice blob/water drop things around him though, where'd you get it? The text looks kind of weird and is not matching with the overall picture, in my opinion. Then again I suck and have no social life.
