That's a very length process, it can be done with only 2-3 layers if needs be using the eraser at low opacity/flow. Not saying this isn't a process that works by any means.
Thanks for taking the time to help some folks and this section out KS
oh yeah, for sure. like i said, there are tonnes of different ways to do this, this is just one of the ways i use sometimes. I like the extra control you get with more layers however i dont think ive ever used as many as i did here hahahaha.
EDIT: Plus it give me the chance to introduce a few features of photoshop that some people might not be familiar with
