Voted Taavi's, I like his scene the best. The lights and lighting are great, though I have to say Taavi could've added some more shadows (because of the multiple light sources). I feel that AudiBG's edit was the most ambitious, but the more I looked at it, the more mistakes I pointed out, the car being the biggest.
BTW, if I win this, I might not be able to provide a theme for next week, since I'm not around. I'll be home briefly on wednesday, and then I'm off again for the rest of the week or so.
Anyways, thanks for all the votes, guys! Really appreciate it!
