Imo it would be better if:
1. You change the spacing of your consumables bar and buffs to that of your actionbars.
2. You change the skin of buffs + totemtimers to that of the actionbars.
3. You change the nameplates shadow offsets so the text looks the same as the UF's.
4. You totally remove the background panel for chat, as in my opinion it's useless aesthetics.
5. You make your DPS/Healing meter smaller (do you constantly need to see so many?)
6. Make your raidframes a bit smaller :P That and your mana bar doesn't have the pixel border it seems.
Just some small details
