I'm creating a posable model of Timothy. His body/torso, hands and shoes are made of fimo clay, and the rest is sewn with felt. The head is able to be attached and removed from the body via several sewing needles, so can be changed. I can use the sewn mouse head, or the clay human head for whenever I wish to change Timothy's species. I'm also making removable clothes. His undergarments consist of a white long sleeved shirt with a grey waistcoat, and grey trousers. This includes a collar of white. Upon that, and removable, is his black overcoat and the shoulder cloak he wears. He also dons his customary scarf. This way, I shall be able to create other clothes for him...such as a smoking gown...and such...and they shall be removable. He is extremely thin, yet I haven't been able to make realistically proportioned models before and I was focusing more upon achieving a right size head.
Anyway...not yet finished but looking somewhat good.
Equipment used;
Fimo clay (for the hair, face and shoes and hands): brown, white and black
Pipe cleaners (for the arms and legs): white
Felt (for the clothing): White, Black, grey, blue and gold.

Update
Ive made a new body for Timothy/Florizel, with better anatomy. The clothing is still coming. I used fimo buttons for the white shirt then thought it looked awful. So I'm going to try using Velcro. Never used it before. Hope fervently it works.
Anyway. Here are some photos of him in two poses.

My sister says he looks terrifying...:(
