Well, first thing I notice is you have 3 timers for your totems, and two for your weapon buffs, and two for your lightning shield. What I'd probably do personally is kill the timers on Pitbull, and move your forte timers above your player frame instead. I'd probably turn off the weapon buff display in totemtimers, since those are long duration and easy to keep track of in the buff frame. With the weapon buffs gone, your totem timer frames will be the same number as your action buttons, and you can line them up better.
I would put the cooldown bar in forte below your action bars, looks a bit lopsided being so much longer and above them. Ideally you'd make it the same width as the action bars, but I'm assuming you have it that long for visibility reasons, so keeping its length below won't look horrible. That may make it more difficult to see, though.
I'd also probably turn the incoming heal bar off for your player and target frames in Pitbull. I've always personally thought the overhang on overheal looked tacky.
