Wow!!
I ran into the same "issue" with my Jim Clark Elise.. in the side view , there is NO yellow, so I Welcome the yellow! The next question is the green.. the originals were British Racing Green, on the Emira it is a metallic green. Not sure if the contrast is better... (of BRG to Metallic green) I tend to think so.
The only thing I would like to see if it can be incorporated in the design is "INDY" somewhere.. mainly as to my knowledge, this was the only Clark tribute targeting the Type 38 Indy car from Lotus.
Maybe it could be the "JIM CLARK INDY EDITION" ?
Edit.. Really liking the bottom one of your designs.
Other choices ?
CLARK INDY EDITION
JIM CLARK WINS INDY ... WON INDY???
P.P.S Edit...
I wonder if JIM CLARK 1965 would work? It implies his greatest year, the 82 covers the Indy car...
