Looks great! You can't go wrong with crypts in a setup like this. I'm a moss guy, so I say more moss for all! More moss everywhere!
But I'm with others, you need to bring the rocks down a little, actually they look too uniform is the issue. Why not try a smaller craigly rock in the middle more towards the front.
The shape is more pleasing to the eyes. Your driftwood actually looks identical to a piece of rock I have in my 2.3gal tank oddly enough. Look at it in the 18" link, as it is the aquascape I think you are going for.
Also on the spawning caves, the fish might appreciate them more towards the back behind everything? I'm no expert there.
