Questions-Thoughts/Input On First Drivetrain Design

Overall, that is a solid chassis. I do have a few suggestions, however.
Right now, your AM Shifters are relying on the bellypan for all support. You can easily fix this by lowering the height of the frame such that it lines up with the top of the shifters and flanging it over, allowing the frame to rivet into the shifters from top and bottom.

Your pocketing isn't as efficient as it can be. Based on the style that you seem to be using, you may want to try a 118-esque Isogrid.
You could also go with the ever popular (254+1323+233+ many other teams) diamond style bellypan pocketing.

Other than that, it looks like a solid start to a drivetrain. Good luck!
