Nice, but the render seems like it was placed there and then some of it was erased away to fade. If you look at the bottom left of her, you can see that it was faded away. If you wanted that look, ok, but I personally am not a fan of that. But otherwise, good job. You do have that mistake with Flinal fantasy in your first one though. haha
I like the bg, but the render doesn't really blend iin all that well other then the blue brush marks, which i think are too obvious, and distracting. Plus its a litlle distracting. The first ones text looks good (other than the spelling error) but its too far over.... just push that a bit towards the render. in the second one, the text is too much of a distraction from the focal point. anyways its a good sig, but there are definitly areas you could improve in.
