As always, your skills make me green with envy lol. You're a wizard with the markers.
As for the design, front end is absolutely great. Not one thing I would alter. The back is great too, but as this is a B.A.T I would expect more madness really. Wings, vents, e.t.c. Though I realise that designers stay away from the LSD these days lol, so everything's more restrained.
Could be more adventurous. It looks like an 8C in the front. And by covering the rear wheels u have made something that should be beautiful look rather ugly. I think the rear wheels of cars give the car a very strong posture and by covering them it looks crippled almost. Ur rendering is good. But u need more reflections to enhance the body surface of the car. All in all its too similar to the 8C an i dont think alfa would ever create a car that looks like an 8C as its an exclusive car so would.nt be very smart to create a similar looking car. But ur skills are very prominent
