I had to re-look at this. Simple backgrounds rule. Excessive "noise" ruins a lot of decent photography. Cute pin-up pose and dramatic viewpoint of car gives it depth and excitement. Simple monochrome palette makes it more universal. The other ones are nice too. I'll hafta get some rat rod photos and draw one of my pin-ups on front. I think we are both heading towards the same goal by different methods.
Thank you Francois. I appreciate your critique. This drawing was inspired by one of my first pin up photo shoots. I was fortunate enough to get a model who was not only patient with me but was keen to please.
