Looks nice, I like the shot where the mint goes in to the car, much better than the other edit.
The stairs at the start look a bit boring. Maybe give them a chamfer and change the texture? It's very dark and spec-y. It doesn't read very well. The mint is also pretty small on screen, so maybe tighten up the shot a bit or make it stand out more.
Overall the entire ad is pretty dark.
Car doesn't look like it's going very fast at the end. Needs motion blur and a faster speed to make it look like it's really racing instead of doing 20 mph.
When the lid comes off the mint container shouldn't it bounce a little or something? It's falling on to what looks like concrete so it shouldn't do that kind of thing.
the bouncing of the mint looks a bit unnatural
when a car fishtails like that the front doesn't move so jerkily, and it doesn't usually move that much. Is the car fishtailing or swerving to warm up? I can't tell, it looks a bit unnatural
the text at the end is terrible man XD
When it goes from R to Racermints, you should make that text 3d, it doesn't blend in with the lighting at all. The background when it goes to the text part is pretty bad too. I really liked that final vista when it's got the big R and the sky and such, are you sure you can't keep that part a bit longer?
Great work
