Hey there !
I have been filp-flopping on what movie scene would be the best scale and time-wise, but I finally settled on the bathroom scene in the first Saw movie. I think the lighting is very interesting (although very blue) and the textures are very detailed. As I am currently very busy at work, I have no clue if I'll be able to finish, but I certainly intend to!
I am also not a character artist, so I'll probably be removing all the bodies/characters
Good luck to all !
