The main thing that makes them stand out to me is, they're really curvy while the menus themselves are made up of mostly sharp angles and slight curves.
The menu needs more curves. Too many angles is boring. Drawing a bunch of straight lines on the screen and saying "Oh look, it's done" is kind of easy, but it doesn't do much for aesthetics. Look at architecture, the most interesting buildings always have curves. http://www.bc.edu/bc_org/avp/cas/fnart/fa267/flw/guggenheim03.jpg, and http://www.archithings.com/wp-content/uploads/2008/11/Tower-Gate-Capital-Abu-Dhabi-4.jpg http://4.bp.blogspot.com/_-5Cl9WHU-Uo/SgqpyS5CjeI/AAAAAAAAESk/5SCi-g9M7do/s400/dubai+(9).jpg http://www.washroom.co.uk/images/news/Aldar_HQ.jpg. You can't honestly tell me that those are buildings aren't as nice to look at as http://3.bp.blogspot.com/-HPPzDQtmyJQ/TndUURo6gEI/AAAAAAAABtA/lsXoFgnbYGk/s1600/world-trade-center-before8.jpg.
The other concern I have regards the icons in a way, but has nothing to do with their design, but their placement next to every item. If I'm browsing the potions I don't need a potion bottle next to every item to tell me they're potions. It seems kind of odd to have those still included in any section but the 'all' and 'favorites' sections, and even then were it optional I'd turn it off there (I can see the point of them being there, though, so having that as an option shouldn't be any big concern).
To this I must point out that, when made possible, each icon can represent the slot that the items uses. Rings, amulets, armor, boots, sword, knife, bow, etc, etc. So having a spot for them is a good idea. Plus, I do believe that it's bad design to have inconsistent implementation, ie what you suggested in having them in some menus but not others. I'd rather have useless icons in some menus than have them in a few, but not others. I do agree that, when possible, a way to turn off certain elements would be nice.
EDIT: So, some of my stuff has been addressed already, but that happens sometimes when you take time to put thought and research into a post.
