What should an aspiring sculptor keep in mind while learning to sculpt?
One of the most important things is to practice (making mistakes is one of the best ways to learn). Experiment with a variety of tools and techniques to find out what works for you. You can take sculpting classes, but you can also teach yourself how to sculpt as I did. Read as many books on sculpting and anatomy (human and animal) as you can find. Study other sculptures and try to figure out how the artist did them. Use visual references such as photos and illustrations.
