I think your tank looks great. Have you considered the fox face and hippo tang. Both can grow large, and the hippo can be agressive. I would think a 34 gallon is too small for these fish?
I had a baby hippo that grew to 5-6 inches. I had to take the tank down, trying to catch him and get him out of the tank. Tougher as tank becomes more established with corals. Also, my hawk fish ate my cleaner shrimp. Do you plan on having any shrimp.
Also, seems like your fish are heavy on the bio load. You may get a problem with nitrates and phosphates as the tank matures. Are you using a phosban reactor, etc.
Again, tank looks great.
