Warlord, your never going to progress in your modeling techniques if you don't try new things every once in a while.

Doing the same thing over and over will get boring, and your limiting your potential, its a very narrow view of things.

Just try a small thing, that if scrapped you dont worry about, yes its bad if you lose 10 or 20 hours worth of work, but you will never achieve new goals if you stick with the bread and butter.
