" Artist's Comments "
"A Silvia S15 chop I made using Corel. Custom kit completely brushed by me (allthough influenced by already existing ones). New backdrop and whatnot"
On the plus side you didn't say it was your car! but even so you shouldn't use peoples work without permission and you don't have NOM15's i can guarantee that.
