Thank you! Whenever I look at them nowadays, I only see the faults, so that's a really kind compliment!
I use a free software called MakeHuman for the base model, but I do a lot of work in Blender and Gimp to prepare the model and textures for gameplay.
Oh thanks, i didn't expect you to respond lol but that's really helpful. I'm working on my own fetish game and this is really helpful. Also, as an artist I get that feeling of only seeing faults when you work on something for hours but genuinely these are some of the most impressive graphics I've seen.
