Looks good Has a nice "breaking off cubes" effect around the edge. It's easy to read and is to the point. Although, you can't tell that the "o" in "0wner" is a zero and not an "o". (Or is it a capital "O" in your name?).
Yep vouches and profile need a different font and colour choice. You nailed the main text though, good 3d and effects. Colours could do with a little work.
In addition to what Kovan said, you could try to add in a Lens flare (Assuming you brought it to photoshop after), but please don't use the stock flare.
Also, just on a side note, your link to your vouches could be shorter.
Looks very nice. The "O" in the word "Vouches" is a bit distracting though since it's filled in. Fix that and maybe another color and I'd say you're good to go.
