You really should have come here before you started cutting up your frame.
It looks to me that you have burned through the tubing where you've installed the flat brace at the rear and there is always a question of tire clearance when you replace raised braces with flat ones. It also appears that you have not internally reinforced the tubing where you have cut and welded in your modification, the tubing doesn't line up in some cases and the welding itself looks questionable. Remember, your life depends on the quality of the work.
You did not see any of the real experts (of which I'm not one) here chop up a bike in this manner.
