As for the price it is really ok. I know there are many painters who do it cheaper, much cheaper. but I dont know how anyone can be under 100 Euro for a single body.
I need for a body like this between 6 and 10 hours. If I have to disguss the design first and draw some scatches than its muuuch more. To be fair for me it is a hobby and I could be faster if I had a permanent working space just for airbrushing but it will never be 3 hours. I painted for one pro driver last year and for me that was already too much that it would be just fun. So many good painters already quit.
Maybe its much for a body but if you look with a painters eye on most bodies you see at races there is not that much time in them, bitty design and JN are super cheap and very clean but on most jobs you can see that they have to be fast to offer those prices.
My painting style is influenced by the japanese painters and I could get close to it but to be honest it will always be a difference. When some good painters copy a Jorn Neumann body it will look different too though they might do a better job than the original. TD uses very many different colors and only he knows which color he used and how he backed it. This looks like Faskolor metallic blue but I bet it is not.
