Those are simply amazing Harry. Do you sell the finished items or is it simply a passion you have? I for one would have no problem purchasing something of that quality. Great job!
I can't wait to see one take shape in your tutorial thread.
So far I've only done them for fun.
As one point I was seriously considering doing them for a living... that is, if I could sell enough to actually make a living. I was going to set up a website and offer "Car Portraits"... you know, the customer sends me a photo of the car they want done, and I create a "portrait" for them using their photo as a reference. But given the time it takes to do just one illustration, I'd have to charge big bucks in order to make it worth my time, and the amount I'd have to charge for each portrait to actually make a living doing them made me think that there wouldn't be a big market for them. (I had intended on creating one-of-a-kind, original illustrations for every customer, not copies or prints of previous illustrations I had done. Each one was going to be "custom.")
Maybe classic car collectors or celebrity car collectors or just people with money to spend would be interested and willing to pay what I would charge for a portrait (Hey Jay Leno... are you listening?)
But my idea never got beyond the "idea" stage... Maybe some day I'll make a go of it, but I haven't so far...
