MH, Just out of curiosity, why are you showing CG cars on a photography forum? I've done a fair amount of consulting when CG first started to be used to render vehicles and my take on it is that unless there are no vehicles available it's better to shoot them. Of course I'm a bit biased! Fortunately, my clients are returning to photography, none of them ever professed any love for CG but their client would force it upon them. Now even the manufacturer sees the advantage of photography (thankfully). Attached is one of my recent images. Jim
Sorry for the honesty, but I think your kinda coming off as being arrogant here. It's obvious this guys new at rendering. And if he's rendering the files himself, there's probably an even greater curve for him to get past. I think the work has some fundamental issues that you addressed in your earlier post, but I think your delivery of the message is off.
I think MH should be on a render for feedback and maybe he's interested in photography feedback here? I don't know, not a regular visitor to this forum. But with your experience, I'd think you'd be more forgiving because you were in his shoes at some point, like all of us...
I think this guy should work strictly on the background, get a look down and get it dialed, then use that to inform the lighting of the car....
With regards to your drop shadow on the car, if you look at the shadows in the foreground you can see that the shadow for the car does not match the scene. I would work on that to improve your image. I'm not sure, the car might not be in the correct perspective. Can't tell with the shadow.
