What don't you like about them?
Only thing I can think of is that they need a crap lot of space that contains nothing, atm.
You could use the rather large spacing in between them for your advantage and put in more information, mainly debuff/buff tracking, either with tags or an aura filter.
I'd try to get rid of some horizontal spacing, maybe reduce the artwork on the sides a little or replace it with something that has less width.
Edit: Meh forget it, you edited while I was typing.
