The marker light change is subtle enough that it doesn't detract and bigger wheels are in keeping with the original design that used 8" & 10" x 15" (because that was the big tire size 50 years ago....).
FWIW, about the only change I would make personally is to add a subtle front spoiler, modify a bellhousing & clutch for more ground clearance, rake the car slightly and do the upper rear link end change like Johnny Woods did, for more consistent handling. The Goose rear suspension is a virtual copy of the better handling GT-40 except for that link end.
