Read it all! It seems pretty easy to understand, but I get the impression this isn't exactly a newbie tutorial - you might want to add something to your description here to the effect that people might need to research in brush effects such as scatter and jitter (so that people who don't know those can read up a bit first and then read your tutorial).
It's really much appreciated, I think it's wonderful that you took the time to make this! The bit I'd have had more difficulty with, believe it or not, is how you add a certain kind of light at the end! I will certainly try it out now that you explained it! Very good use of pictures and steps.
THANKS SO SO MUCH! And great job as usual!
