Said this in the sbox, don't know if you saw it or not.
There's a stroke 1px around the avatars.. it should really be gotten rid of or made the same color as the miniprofile behind it. It doesn't seem to fit the avatars right, especially if you do something like the rounded corner on mine, which is probably what i would do with stock avis.. that and i just don't think it looks good from a designers standpoint.
