I have rarely had more fun testing out/ 'Hobbying' as my lecturer used to call it than when recently trying out digital sculpting in Zbrush. It has got me hooked and I intend to learn this along side my current modelling / lighting tasks. It may slow my initial learning down but it is great fun and is helping me get more of an interest in organic modelling.
Below: Adding ears and some room for the eyes (need to work on ears!). No Reference
Above: A turntable of my first attempt at a torso. No reference.
Finally for those also interested in trying it please remember instead of saving the document you save the tool. I lost the above torso after wanting to do some more work on it today. I must have saved the document in error. It gave me another go at creating one from scratch though.
