lookin good I would add the one other baffle on the right like the first sketch, one other thing i would suggest, at your fuge baffles i would take the one closest to the pump and bring it down to the bottom of the tank and bring the height a few inches above you pump, just a short baffle, what happens is when your sump is low the water coming out of your fuge creates a waterfall effect down to the sump water and makes a lot of bubbles, this short baffle will help trap these bubbles before the go into your pump, I learned that lesson the hard way on my first fuge.
