There is less time for creativity for a lot of us. I'm 25, I can't spend 10 years learning to sculpt right now so I can have the custom House M.D. head I want at the quality level that won't get made fun of as you point out, when I'm 35.
Then I'd have to spend a few years learning to paint and sew. If I'd found this hobby 10 years ago it'd be differant but things have evolved so that others can now offer stuff like headplay and I don't need to learn what to do. BTW materials, sculpty, etc, you think that stuffs cheap plus learning how, far cheaper to buy a head cast.
I'll take a custom in 2 months time from 3-4 people who are incredibly talented and be just as happy.
Next time you need a flight to wherever, stop and think are you less creative because you bought an airline ticket instead of building your own plane and learning to fly, or is it just far more practical because you already dedicated your life to learning another skill.
Les, Josh, Chris Howes, all brought it on themselves with greed. The end.
Proof? Elvis. Knew he had a kid coming, said sorry no more commissions right now. Responsiblity and alot of respect is what that showed me.
