Not bad chap!
I think I'd have used a slightly larger DOF on the XK8, but that's down to personal preference.
I think the only other thing would be to keep the shadow within the bounds of the photograph, that way it can be used on a plain white page without any alteration, which a designer is going to thank you for!
Edit: I know Diesel use some strange design elements sometimes, but I can't tell if the bottle is #3 is OOF or not? Must just be my tired eyes!
