Fear! Lol! Fear of Lucasfilm taking everything I own due to IP copyright law... Since then I sculpted a Kylo helm that was pretty popular on the RPF... And the powers that be have let me live. Haha... I may do a mold of Yoda if I get really brave! Haha
...plus the other point, I enjoy being a fan! I LOVE sculpting but I HATE producing. Lol ...I hated having to produce a bunch of Kylo Helmets... It took the fun away . I don't know if that makes any sense.
