I can't imagine I'm the first to try this, but new hobby acquired:
I ran the ones below on the spot and it was quite fun. Before this, whenever I visited the British Museum (a few times a year), I didn't really give most of those statues a second glance.
An exercise for the reader (this one's interesting because they put a reference of what it could have look like if it were complete based on a different statue):
And another bust of good old Caesar (might be interesting as there's so much reference material, and it's so broken):
Try it and have fun! I'll try another batch the next time I go.
