Where did you learn to draw like that? Your portraits are absolutely stunning!! So realistic they look like black and white photos. I'm totally amazed at the work that must have gone into it.
I started out on a forum, like this. Run by a guy named Brian Duey, and some really helpfully talented artists.
Having drawn something, I would post it and get advice on how to improve.
It became an obsession, everyday I would draw, everyday I would get better.
Sadly, that forum died down, as everyone left, dazzled by the bright lights of deviant art. The shame is that the guys there really wanted to help.
I then just went on to surf the web, looking for any tips on drawing I could find. Tutorials for drawing hair, skin, clothing...etc
The Internet is a wonderful thing.
I study better artists than myself, and try to work out why their drawings look better. Armin Mersmann is the guy I look up to most of all. His work is phenomenal.
That's it really, no tricks or secrets, just the 3 P's (practice, patience & practice)
I was lucky to stumble on Dueys forum, but this has the potential to be just as good a forum, and if I can help out I will.
