You mean the roof slope? That would be good. Extending the roof line as you've done will give you a small benefit, but you really want to continue tapering downwards.

Without even doing the "ideal teardrop" photochop, I'd say you could confidently increase the taper to around 10 degrees more than the roof angle just ahead the attachment point.

The good news is you don't need the photochop: you could put tufts on the plexi and play with angles to ensure you've still got attached flow... immediately verified in your rear view mirror!
