sculpt timelapse video:
wow great timelapse, really good anatomy details too I liked it.
may be a personal taste, but far too skinny for a batman, technique wise, can’t comment as I am nowhere near that level 
Thank you guys!
Aionard: true, its a very skinny version, but there is so much and i thought it woiuld be a good choice for the overall mood.
