The latest project at university, where I am using Zbrush to illustrate the digestive system, as part of an educational book. This is a test render of what I have done today, with more to do tomorrow, and so it might change a bit yet. There are some membranes to add,and also the mouth section. I haven't posted on here for a long time and so decided to share my progress with this as Zbrush is excellent for organic shapes. I used Zspheres throughout.
