I like to use Photoshop to draw (mostly because I'm not very good at coloring without the computer). Here are some examples:
I drew this loin when trying out making traiding cards
Inspired by a CD cover...
trying out a new style

i drew this first to go on a hoodi i'm painting but i liked it so much i redid it on the computer

this was also for the traiding cards ( which, by the way didn't work out)
