I remember review one of your earlier designs months ago. I remember back then you had like 6 or 7 different shades of the same color.
But now that I see this,
I can tell you have spent a lot of time improving it. It looks much improved.
The only thing that pops out at me now is the inverted blue nike swoosh above your main text area. I am only mentioning it because most of your other graphics have much more depth to them (glassy looking links, or beveled footer). But the swoosh just looks like you stuck a drop shadow on it and moved on.
The same goes with the company logo. Drop shadow then moved on. I know you can't change their logo but you can definitely upgrade it to match the other sleek effects you added elsewhere. A simple gradient, bevel, or glass surface could greatly improve the nike swoosh and/or the blue arrow company logo.
