looks pretty alright; here are my suggestions:
def needs a different background. way too distracting. if you wanna stick with the current pattern you could probably subdue the color (a lot), and/or add some gradient type thing, like this maybe?

the dudes with the speech bubbles seem kinda haphazard compared to the rest of the site. consider organizing them a bit more orderly, or just remove them entirely and stick with good ol' fashioned text blocks.
as for the profile thing, it needs more padding around the edges in general, and the bottom of all of the elements should line up.
