Wow, amazing work! Expect poster orders when I remodel my house
Any chance you've got something coming up with an LCI e60 M5 taillight & quadpipe in view? Real 'glossy' perhaps in black sapphire/blueish. Judging by the styles in your gallery i think there is no one else that can pull this off the way i imagine it.
I think the contrast on these tails would make for an awesome drawing.
