In general, looks really good!
What thickness sheet metal are you using?
Where and how does the bellypan mount?
What drop are you using?
You might want to do a bit more overlap between the front frame member and the 4 "drive channel" frame members. Looks like you only have 3 holes within 1". Getting even another .5" (or preferably 1") would be great. Your bellypan and material thickness might make this issue less significant though.
I'd recommend having a few standoffs or stiffeners going between the inner and outer plates of your drive channels. A couple of these in strategic locations can go a
long way towards reducing stresses at your other joints.

Seconded...

Agreed that this does weaken the frame, but if the belly pan is mounting on each side of the gearbox, the sheet metal thickness isn't on the low side, and they add a couple drive-channel-stiffeners, I think the way they have it would be fine. That said, I've only fabricated one sheet metal drivebase (despite seeing dozens and designing a few). The s-bend can be a neat fix, but can also make accessing the wheels fairly annoying.
