@thecabbagedetective You just never cease to give these assignments 110% effort. I gotta give you a A++ because the quality of S&L including textures for both renders, which was not expected. Good stuff dude.
As far as including your limo in your portfolio, Thibaut offers excellent feedback and I affirm the opinion that this is some of the best finalized work I’ve seen from you. Considering that, I’d say yes put it in your portfolio! The only suggestion I can make is that you revisit your road material to look less low-res/blurry, more realistic. Check out Mahir’s road for reference and maybe he’d share some insight.
