I like the effects and overall style. As for CnC goes, it looks a bit flat overall, you kind of lose the definition and focus on Ezio. He needs to be a bit brighter and sharper to add to the focus and depth of the sig. The 2nd version is better btw, the first one is too dark for sure. I'd play up the lighting a bit in the 2nd, you have the light source on target but perhaps make the lighting less subtle? Lastly, the size and placement of the text seems off to me. A light font, slightly smaller, in the dark area of his cape on the right side would suit it better, and not take attention away from your focal.
Overall, pretty good sig that just needs some tweaking ^^
