I'm finding that stippling hands takes a different approach than an element - say, the snail - that is made up entirely of dots. Keeping so much white requires more sensitivity when deciding where to place the dots...and there is more 'consideration' involved. So, the process is actually a little slower.
I'm trying to decide if i should use color (a light wash) on the snail. That was part of the original idea...but it's also what ruined the first attempt with the tree frog. I probably will use color...i'll just start with a super light wash and build it up slowly.
