Nice looking tank, I can see you closely followed unirdna's photo advice. The pics look 100% better! Agreed that the driftwood setup should be placed at a ratio of 2/3-1/3, not right in the center. This would be easy enough, and you'd be surprised at how different the tank will feel. I like the buddha.
As far as your planned layout of DH and riccia . . . try again to follow the 2/3-1/3 rule. For example, I would try something like this:

It just seems less symmetrical.
Also, if I were you i'd try to get 3 sections: fore, mid, and back grounds. the watersprite and ludwigia are great for midgrounds, but try for some contrasting and taller backgrounds!
Looks great, keep it up.
EDIT: I have the milwaukee regulator (same as the aquatraders.com one above) and i love it. been running for 2 weeks, and no problems. If you want the extra timer, then maybe go with DRSFOSTERSMITH, it also has the tubing. But if you don't need these items, stick withteh aquatraders. Also, will that light fixture FIT under your hood?? i've never had a bowfront, so no experience there
