This is the full image from the last post, with tonal values splashed on there. It's still a work in progress, but at the moment I'm working up a solid value relationship before I start to tackle color. This was a tip I learned from watching one of J.P. Targete's videos from The Gnomon Workshop (quite possibly one of the most helpful videos I've ever seen from them.)
The actual idea for this came about from listening to one of Bobby Chiu's video streams. Somebody suggested he draw "a toad crossed with a bat," and when he decided not to take it, I thought it'd be a waste to let a weird idea like that slip away. So that's how this came about!
