I used to draw a lot more than I do now. Part of it was that me and a few friends would regularly hang out just to watch cartoons and draw all day. Another part of it was that I was playing games more frequently and had more characters in my head that needed visualization -- a good excuse to pick up a pencil and draw if anything.
These days, I'm less inclined to just hang out and draw, but I at least have characters that need drawing again.
I'll start with my own character -- Rat, a Tiefling Artificer from the lower levels of Sharn, City of Towers. Having grown up an orphan in the slums of Sharn, Rat's intense curiosity, brilliance, and natural affinity for the arcane led her to discerning the secrets of artifice herself through junked automaton parts and discarded notes from the more privileged minds of House Cannith far above her station. Not one to be picky, Rat spent whatever time she wasn't foraging for food or evading police or street thugs tinkering with her collection of trash until she had finally succeeded in assembling her first working automaton -- a homunculus named Skitter whom she keeps around to this day, adjusting and upgrading him every so often for the heck of it. From there, she graduated to more complex and varied contraptions, though her specialty remained in building automatons as she would regularly create little friends to keep her company. She gained some notoriety in later years as the local "junkificer" before she built up enough knowledge and practical skill to venture out of the slums and finally make a name for herself.
One that didn't sound like vermin, at least.
