Not sure if it's common knowledge or not, but when a company approaches an artist with the intent to produce a figure, direct monetary compensation is rare.
Rather the artist usually gets a percentage of the run of toys, to do with as he/she pleases: i.e. sell directly or create customs that would sell for more than the base toy. The other motivation is to expose their art to a potential fan-base increasing demand for their art as a whole.
This is why, when you have the opportunity, buy directly from the artist as your $ will actually go towards supporting them, & not the company that produced the toy.
And today just such an opportunity arises as Dok A has the Asian exclusive version of the 8" LePodd: 'Sweeny Podd' available on his store. Buy it, as it's sure to be gone soon.
