Usually I sculpt in Blender. But I've wanted to give ZBrush a try for a long time and last year I finally downloaded the ZBrush Trial version (free to use for 30 days) and started practicing. Of course you don't become a ZBrush specialist in such a short period of time, but at the end of that month I was already able to sculpt these 3 famous creatures. I was very happy with the result. I thought I should definitely post this here.
One additional advantage of ZBrush is that you can record your sculpting process. I then edited this playful, accelerated video and posted it on YouTube.
The video lasts 4 minutes, the real sculpting time was a few hours.
