I like the colors, but man you have waaaay to many things going on there.
I have no idea where to look. You should try to simplify things and work with shadows and blur. This would create focus and depth, which is essential. Often, less is more
It's OK. there are too many things though and it's doesn't have a unified "feeling". I mean that it doesn't really have a main texture or pattern.
is it just me or does the render not blend in well? (that really dark brown stuff, has no echoes)
any of the themes that are represented there look like they could work really well alone. a little bit of work and this would look really nice.
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
