It makes sense now. The tri-color I personally think is a grey area, but the storm-trooper thing I can see why people are claiming forgery.
My opinion doesn't matter anyway but I do respect art. I can see where the problem lies as well. People are much more willing to buy duplicated keys than they would a duplicated painting which affects the resell value of their keys made by the original creator. That isn't really fair especially if people are buying them at inflated prices due to rarity.
I mean, if somebody can create respectable replicas of existing designs. the original design doesn't seem as illustrious as the overly inflated prices suggest.
People make and buy replicas all the time. If it means you can get a quality, cool looking product at a cheaper price, that's cool with me, the consumer.
Why can't it be a tribute to the original artist's design? Like a band that cover's another band's album.
He's still forging the caps himself and partaking in artistic creation. If you have a problem with that, don't buy them and continue buying the original for their steep prices. You still have plenty of people who will do the same and prefer the original designs, so price inflation shouldn't go anywhere. There will just be two markets of consumers; one that enjoys the exclusive feeling of acquiring rare art, and one that doesn't care about that and just want a cool looking cap for their keyboard.
Stop pestering the man and go make some new designs yourself.
