OP: really nice job you did there.. I like the incorporation of newer BMW designs such as the headlights from the X6 etc. Honestly I much prefer it over the E8x/F2x designs. Nicely done. Also fills a niche not currently offered by BMW and few other automakers (the 2 door hatch). I'd buy it.
The only thing I would change is to remove the sloping like on the lower side doors, and replace the skirts with ones that taper to a middle arch (aka the M3 side skirts) to give the impression of a sporty/lithe side profile.
