My honest opinion mate is that this needs a lot of changes as is - there's way too much going on IMO on the exterior where it looks disjointed and some of the interior detail needs more consideration.
Take it with a pinch of salt but this is what i would do:
The livery looks way off - giallo like you said would look better.
Axe the 63 on the front hood.
Brake Calipers to match the livery
Consider changing the A Pillar to body color.
Rear deck lid and upper intakes need to be body color IMO - not enough blue on the exterior with all the dark carbon
