I'm 6'4"! Looking at yours, you have your seat set back a bit further.
I think that color combo would really pop, and not be overdone. Personally, I think keeping the gold to a minimum on the tins would look classy. Maybe even some gold leaf. The rear fender/cowl is yelling for some pinstriping and you can even add minimal striping/leaf to the frame to pull it all together. Dunno, just thinking out loud.
