I'm glad you liked it, I put a lot of effort into it.
It took several days, I didn't keep track, but it does take work. Thanks to the skeleton the figures can be kept for a long time, but you have to keep in mind that it is plasticine, not a really hard material like plastic, so you have to treat it like a delicate piece of fragile porcelain, let it sit on the shelf without being touched too much.
