I like it a lot! The only thing I am not fond of is that now all user and Moderator names are blue. D;
Love the new background image. The new style I would change a few things. Either change the default name color or change the moderators name color. They shouldn't match. Add a home button when clicking the mineverse logo. Work the staff online to the front page. Why not keep the old style with the new background? This style reminded me of .net and that makes me sad. One of the best things about MV is that we are nothing like them. I think our style/theme should stay original to us.
I think it looks ok. I'm not a fan of the deep blue, yet it is easily changed for the people who don't like it :D. Also, i'm on a 15" Non Retina MacBook Pro screen, and it doesn't fit that well to be honest. The logo goes into the Home, Forums, Rules, FAQ etc section. And it seems like there is probably more artwork being blocked by the actual site. What @Keith </3 said, also I guess you know, but the logo isn't leading anywhere
I think it looks very good, just center the Mineverse logo, add a portal page, and hyperlink the logo to the portal if you do get one, if not, link it to the XenPorta page.
