Looks good. I see a lot of room for more coral!
oo you might catch some flack with the Mandarin, they have very special needs that are worth looking up.
I'm not trying to shoot your list down, I'm not one of those people, but I think you will have a hard time getting that many fish in that tank. The old freshwater rule of thumb for 1" of fish per gallon doesn't really apply here. It's not so much that your tank can't handle the bioload, it is the fact that saltwater fish can be very territorial and it is more of a behavioral thing.
You do?
I'd you can see rock that's a place for a coral. I think it is kinda empty.
I would get a purple firefish and orange prawn goby in addition to your clown.
