They look how they should. A couple things bother me though, the paint doesn't look like an exact match to the rest of the car (i know how hard it is to match white though, and it's very close). The other thing is, i think you should have gotten replica fiberglass ones since you were going to paint them white anyway. Painting carbon fiber ones was a little bit of a waste in my opinion, unless you had lots of carbon fiber parts to save weight (like doors, hood, trunk lid, etc)
none the less they look nice, and i dont think you'll see too many e30's with those mirrors around toronto =)
now what i wanna see next is the whole ///M stripes and the rest of the stickers. As well i'd like to see your exhaust come out the sideskirts, that would kick ass.
