I guess I read your opening post wrong. I thought you were an aspiring illustrator/comic book artist. I guess you just like rendering pictures; These links aren't ads, they are the steps that are required for character artist.
I am and I misread the links. I then had a look at the links, but I do not require them, as I have sources like that already and I have a few books to help me. On top of that, I am still going through education, so I have good sources to learn what I need. Thank you for your concern.
