The idea behind the dual lap belts in a true aerobatic installation is that each attach point is to be attached to a
completely different structural member in the fuse such that if there was a failure of one seat belt anchor point, the other one would still hold. In a rag and tube bipe like the Pitts or Eagle, each seat belt attach point is attached to a completely different structural member (tube) so that the loads are spread between two points. Looks like both of your attach points tie into the same structural member. That being said, I doubt you are gonna fly this thing like tucker, with a lot of (if any) outside pushes - where the belt attach points are pushed the hardest - so I'd say looks ok
