looks a little...squished

and the bb's like 3 feet tall

The BB is only 600mm tall
Yeah, if you can read what I wrote, im planning of slackening the headtube and lengthening the chainstays.

Wait a minuite, im looking at the original picture, and it does not look nearly as squised as the scan... maybie our scanner is messed...

That will be so fun to build in real life.

2 shock system reminds me of the old Kestral Rubicon DH(like the one in this link, but with the link under the seatpost replaced with an additional shock):

yeh a slackened head angle and you will be there v nice

hmm.. maybe drop the bottom tube a little lower? or put a curve in it? seems like that would help pull the shock down more which would cause the swing arm to come up, resulting in a lower center of gravity, also you would prolly have to mess with the seat tube/post after that cuz the tire may hit it.. O and idk, but you may have problems with to quick/to slow of rebound, (shock wont be able to go down fast enough because the others rebound rate is slowing it down) and definately try to do somethin bout the head angle, cuz you dont wanna be holding on to the bars all funny, and turning weird cuz its not slack enough, but anyways looks like a good design!

dude! your design is awe some! you should try making a real model of it soon..
