Thank you both very much! I'd love to have them cast some day and see what they could look like painted.
I agree that I made her hand too large. I need to practice hands in general, because even though I think her hand came out okay detail-wise on the front, the other side is a mess. I also made the mistake of sculpting her hand in that position rather than away from her body, so I couldn't reach most of it. Honestly I have a long list of little mistakes that I'm going to try to avoid with future figures. For now the mistakes I've made on her will remain as a snapshot of my current skill and experience level.
As for the knight, I think you're right about the camera angle, but again, I just generally need to practice hands because there are a few wonky things going on with it. I meant for the plate you can see on his gauntlet to be covering the tops of his fingers. He has a larger guard that isn't visible in the picture covering the back of his hand onto his wrist. The way I sculpted the individual finger plates makes it look like either his fingers have too many joints or that his hand is too far forward and bent awkwardly.
Anyway, I plan on finishing the halfling some time today or tomorrow, so I'll be posting more pictures soon.
