It's nice but I don't really like the heads. Could one be male and one be female...and could they be younger people? Right now they look like old men. Also could the heads be made smaller, and the DV Academy text be made to be more prominent in the image, since really that is the main focus. Also what about using blue and white to match the rest of the site instead of green and orange. Were those colors arbitrarily chosen?
As for the massive amount of badges under people's avatars...I really do not like how that looks at all. But I don't really have a suggestion just yet for what might look better. I'm very busy right now, but will try to give some feedback if I get a moment.
