It's a decent signature Shroom. However, notice on the render of Link that you used, that the lighter side of him is on the left side, but your light source is on the right? Yeah. =P

As for the text, I think you could loose the 'Link' in there. If you're going to have multiple words for text, keep it generally together.

For your next assignment I want you to use this render and work on your lighting and perspective.
