Try doing some research on habit forming. Because that's the real key to success here. If you can't turn drawing into a habit, you'll do it for a day or two and then go back to your old ways.
Hey man just go for it. Share lots of work in prigress things and failed things in a thread like this or whatever too. People who are good can critique it, and people who are baddies ( me ) can learn from some mistakes too.
Always nice to see someone deciding to try and start drawing! *_* Practice lots and arm yourself with lots of patience... the first times it can be hard!
