So, it looks like you're getting sucked into drawing just like me - I am also a twenty-something computer nerd who recently picked up a pencil. It only takes a couple years of learning the basics and getting some very intermittent practice - eventually, art stops looking like black magic and turns into more of a procedure. It's really hard, though! I have new-found respect for artists who devote their lives to this craft. However far you go with drawing, good luck, it's a pleasure to watch!
