Aside from what others have said, your rear stays cannot be 2 pieces. Don't waste anymore material, do more homework and have another go at it. A poorly designed/executed bar is more dangerous than none at all. If you sit in the driver seat, in your normal driving postion, does your head (with helmet) extend beyond the top of the roll bar?

Not pissing on your parade, but there are lots of things that don't look good in those pics. Things that would might not make it past tech and could get you seriously injured in the event you actually need the bar to do its job.

Do more homework, safety isn't something to take lightly. Look at other manufacturers and check their designs and look at an NHRA or SCCA rule book and there are guidelines for this stuff.

Good Luck.
