:P Using the magic wand tool doesn't mean you get 100% perfect cut, not even on a white background. Though you would get that bad of a drop shadow from it if you did.

I like the text being bright in the first one. The render does look like the helments pointed to the left his head since your brushing implies that.

The brushing behind the render doesn't go well with this sig, might try more brushing in the bg if you really want to brush.
