Max, you're okay. You're a good guy.

Making something that represents something else is fine on any grounds. This is a hobby and you should enjoy it, not create a moral dilemma.

The real problem is recasting, direct copying of someone's product. I know people that have premiered a new figure at a show on Friday, only to have bootleg copies show up for sale at the same show two days later. Recasting hurts everyone, it drives talented people out of the business while delivering subpar products to the consumers, usually for the same price. It's a huge problem, to the point that the figure community pounces on anyone even remotely suspected of recasting.

I take pride in the fact that what I sell under my name physically passes through my hands. When I first started doing this stuff it was with modeling tools. The company that was manufacturing the tool started packaging it as well. Biggest mistake I ever made. In short order, some crappy examples were finding their way into customers hands. I had to recall a bunch and kept the final packaging in house. The idea that some bozo is copying a sculpt of mine and that is getting into a customers hands is far worse that the theft of sale.
