This is pretty good for a first layout. I've seen many first layout, and they've been less attractive than this. I don't think this is too bad, the background is nice and matches with the tables. Though it looks like it could've been done with the profile editor.
But I have a few pointers for you for next time;
IMO the text used for the navigation is a bit too big, and I see the hover font as Comic Sans MS. I think this font is used a bit too much where it doesn't have to be, but if used sparingly it can look okay.
Also I think the nametext is a bit.. big and distracting?
The rest is alright, though my main comment would be on the transparency on the tables. I couldn't read the about me text without having to highlight.
Work on it and you'll have it perfect.
