Roll Bar Fabrication. Advice on Mock-up Needed

[truegearhead]

I'm having a bar fabbed up for HPDEs, its tacked together now and I'm heading to the shop tomorrow to take a look. Does anyone see any changes that need to made? The seat is pushed all the way back currently, 4-5"s back from where I sit so I'm not to worried about the bar being close to my head in these photos. The other thing I'll note is that I'm going to reinstall the top so the down bars are a little steep to accommodate it. Currently the hoop sits even with the wind shield.
