Are you planning on going back to this anytime soon to work on it a bit more? Proportions are still off and it's still soft in a lot of areas like the eyes.
Does harden/soften edge translate to other programs? If I send a model with some hard and some soft edges to Unreal, will that be obvious in that program?
@Shyralon: Switch matcaps to a gray lambert. The default skin one kind of sucks for looking at the sculpt critically. It makes everything feel too soft.
