Great job! yes with smaller armatures like this I find the hand armatures can be more trouble than they are worth so usually I'll only do hand armatures for large sculptures (like 1/2 life size or bigger) but great job! Keep it up!

Looking good! the thumb might be a bit long and I would work on bending the fingers out to more resemble the shape of the hand (this helps to better see the proportions) and keep going! add some clay to those wire armature bones!

Looking great! the proportions feel right! good job!

Usually smaller armatures don’t need wires in the fingers because the wire gets in the way. 20 gauge is usually smaller than 14 gauge so it might be good for smaller figures.

Hey great job on these!

Hi Dominic, nice tension in the fingers!...reminds me of opening a jar, then one inch punching said jar when it wont open. -I'm super curious, is that a sculpting tool it's mounted on?

I’d try focusing on the structure and primary forms more than the wrinkles of the hand. Try watching Stan’s videos in the anatomy course on the structure of the hand and how to draw the hand, those are helpful to capture the primary forms. Once those are in place then you can worry about the details. It looks like the fingers may be too short in comparison to the palm of the hand (unless it’s a baby hand which has a larger palm but also a larger wrist in comparison to the fingers)
