@Raven you may want to go in and add some wrinkling on that old man's throat. It looks really weird that his face is the age of a 60-70 year old and his neck still looks like he's in his 20's. Also not sure what's up with his ears but as it's not the focus, I guess it's ok. It's a cool render though. Just needs to be pushed a bit. If you have time, definitely revisit it.
