What I can tell you is simple works better. One of our best converting hosted galleries is plain as can be.
http://www.brokestraightboys.com/galleries/videos/1/. I think your gallery has a bit too many colors imo. There is also some good suggestions here from other people.
Even though Broke Straight Boys is everywhere it still converts like crazy. The best way to get even better conversions is to get members access to the site and I can send you the updates before they even post on the site. So this way you can get a gallery up with models that haven't been seen yet.
