I dig the tank!.
From an engineering point of view you've lost all the triangulation in the whole bike except the neck. You've got 2 sets of welded angles in the rear section with nothing to support them in either tension or compression. That = a fold. One 1 good pothole or bump and your nuts will be squeezed between that bottle rocket launcher and the back wheel.
Take a look at a Detriot Bros frame. They use bent tubes not welds Although not perfect triangulation it supports it because they elongated the triangle.

You've also taken the triangle section where the motor sits and turned it into a square with no reinforcement. Remember squares fold, triangle hold.
