The render in my opinion, doesnt suit the style that you have gone for, the mario would fit more intro a vector sig. The colours also don't match very well. And is too full with effects and renders. Version 2 is alot better, as it drown's all the different colours, and makes it look that little bit less full.
All of your sigs are over-contrasted, oversharpened, poorly coloured, and with bad composition and text. I'd recommend you go back and do more tutorials, but you'd probably just get offended.
Like mentioned before, version two is better. In the first version, there's too much contrasting colors going on and it looks a bit too busy. I also agree with Idratio in that the render doesn't really fit with the sig style.
