Well, I guess it could be as much as an hour. I don't remember, but I checked the file properties, and its "last-modified" date was about half an hour later than its "date created" date. I can't imagine spending more than half an hour on it before saving it for the first time, so I'd say between half an hour and an hour. I also spent 5-10 minutes with the poly-reducer brush. The screenshot was taken before I did the poly-reduction, but it looks basically the same now.

I used the smoothing brush a lot.

What's good software for making timelapses? If I find some, I'd be glad to put up videos of future work
