Hi! Welcome to the forums!
The design is pretty sound for a spinner, though there are a few things I'd look at.
The bottom DSL bar looks like it intersects the Perm motor. While not really a problem, is a personal gripe.
I think the weaponry could be improved personally. If you are to do the 2 bar setup, I'd stagger the bars perpendicular to each other, this will make it harder for another bot to hit that piece of chassis.
As for the chassis, try rebuilding the shape to end at the Perm, the area with the weapons in could be shed to allow more weight to put into defence and weaponry.
I think someone will say things about the battery but I am no expert in DSL 2.2 so I'll let someone else do that.
But for a first bot it looks pretty good. If it works, it works.
