Is your goal to simply display your fish in the fishroom, then this is a sweet setup. Possibly my only piece of advice I have to give is to place some kind of swing door where your sink is so that you get a sense of a finished wall through out.
If your goal is to breed, which I do not believe to be the case, you would need a lot more tanks for your fish room.
Either way, this will be a nice looking fish room. Roughly what are the dims and volume of each tank?
