The gearbox pattern might be a little too much, but given the layout it's probably not fatal. The main thing I would do with that is make the webs going to the big pivot larger (5/16" or even 3/8" wide).

The chassis looks fine to my eyes. The pattern is similar to 971's patterns this year, and didn't decrease stiffness noticeable last time I checked in simulation. Given the large square shape, however, adding a wooden bellypan would be to your advantage.
