Here for those who like such things, is the process I stumble through when I create a color drawing...
It starts of course with pencil, paper and vague idea. I try first to capture the "emotion" of the scene in quick sketches till I see one I like.. I did this one first:
I took a second try and wasn't crazy about it.
I didn't really like that better so I went back to original and changed the poses, ending up with this final "rough" with better arm gestures and background critters
Then, I place the scan of the pencils into illustrator and ink them using a Wacom Intuos 4 tablet.
Finished inks are then exported to Photoshop and colored as shown in the animated GIF below.
Exported photoshop image goes back to illustrator for final text. So there you go!
