Speaking on first, initial impressions - which to me are really important. Sure, some things will grow on me over time, but I tend to rely on my first impression.
Rear photo - I immeditely though of Lexus IS-F, which has a terrible rear end IMHO. It's like the ended up with a really big bumper and had a hard time figuring out what to do with it, so added that big diffuser, but not really a diffuser type thing. IMO, shoud have brought the exhaust tips a little closer in, and mover them up a tiny bit, with the fascia conforming to the tips better, like virtually every other M car that has been made to date.... The exhaust kind of looks like and after thought, with the tips hanging down like that....
Front - weird combination of M5 and M3 - M5 in the head lights, M3 in the weird double fang look. Front end is not too bad.
If any design feature on a BMW reminds me of a Lexus -
