looks alright, im just not used to right placed renders n such, the SMG (Super Mario...) logo looks strange, other than that, I say good job.
bring out the logo more and closer to the render. lighting here is really weird and mario could use some sharpening.
I think the text doesn't stick out enough in the corner, it's clouded and that makes it hard to read. I also don't like that Mario looks scared or unsure in the picture. It doesn't bring the sense of nostalgia that it should. I expect to see a brave and whole-hearted adventurer in Mario, not a scared, and cowardice human. Other than that, I think it's great.
