It took quite a bit of fiddling to prevent my nails from clipping through the finger claws, but I eventually got it to work. The texture could be a little darker and/or more contrasted.
I’ve also painted a version with a red base which looked quite decent, more on that later.
I’m thinking of making a few “variants” to minimize the number of separate models used: both hands, left/right hand, both indexes, left/right index… or maybe index + middle finger, or something like that.
There is also the question of adding doodle & strike integration, because… why not?
