I used to drive a BMW, and I must say I never really liked any of the "grandpa"-looks that came about after Rover got in.
This is a very nice rendition work - kudos! - but IMO, I think it has a bit too much "Jaguar" about it. Especially the rear top part. It surely does not look like a sports car, more like something for an old, distinguished man that wants to look a bit younger than his stiff colleagues. Much like most Jaguars do...
But I've seen worse designs in real life, so keep 'em coming!
