My personal thoughts on the sculpting process:
React, feel, interpret, but don’t think. Let your eyes direct your hand.
Learn how to sculpt what you see so that you can consciously choose what to leave out.
Sculpture is volume, look for large shapes first.
Be aware of negative and positive space.
Control the viewer's eye.
The eye is controlled by: capturing light, negative/positive space, the flow of "lines" between elements.
"Line" also applies to sculpture.
Sculpture has black, white and grey, keep it balanced - black isn't always necessary.
The surface should happen as a result of applying the clay, however you can create texture last.
Don’t force a style on yourself, it will emerge.
Learn when to stop.
Look at the work of others.
Use a mirror to see more objectively.
Step away physically and emotionally to critique your work.
While you are learning, have your work critiqued by someone who will tell you the truth.
Cover your work, don’t look at your piece for two weeks - if you are still satisfied, you are done.
Sculpting is YOUR time! It's who you are, you need it and deserve it, so DO it!
