So this is basically the proccess I did for THIS piece.
I do mostly the same for most of my GF art (Asscreed and Marvel are another story because I like to do things different for those). Some times I use less layers, or more, depending entirely on what I am doing. I would suggest you go and watch actual useful tutorials online tho, what I do is a mix and match of the hundreds of tutorials I have read and practiced over the years, so just you know, go out there, experiment, find what fits your style better.
OMG OMG OMG I FINALLY HAD MY PHOTO DONE WITH THE GUYS. They were so kind and thoughtful and they held my drawings for the photo. I will definitely be doing this again.
Jensen: Woah this is awesome
Jared: Wow did you do these? With pencil? Magnificent
Misha: Woah so cool, you actually made Jensen decent looking
