Thank you so much! I'm about to find out if the knee joint is going to work, anyway I think that it would be so much easier to just hand sculpting that part, so I can see what exactly is going on instead of just virtually figuring out what it might be.
As for that I'm looking into apoxie, I wasn't particularly thrilled about it because it works very differently than the clay I've tried before. However I've done my researches and I think I'll buy some to try. It would also be useful to fix the headcap and the elbow joints when the time comes).
