The edges on the top are too dark, and the lighting on the "E" and "L" is too extreme. Try making the lighting more even, that would help a lot. Other than that, not too much to say... Its nice.
idk what to say, really.. it looks really good right now, but i do see one thing odd.. the light source is in the center, but all of the shadows go straight back. i would have the shadows go more towards the side as you get further out
