the black of the hood is way too dark
it needs to have a more light tone at the top
there are just ti little tone / light variations in the black , if the silver is that bright .. the black should go more towards grey tones with brighter highlighted area's
i think you's better loose the black hood all together it just doesnt look that good on a 5-series , next time dont darken it so much as one piece
same go's for the gold paint you made it gold and made it so dark the tone variations got lost and the whole paint / body becomes unreal and doesnt match the rest anymore
also watch your tones / hue colors
on the gold version all the pastic still have strong blue hue's , the gold has not got that , so either the blues should go / be toned down or the gold needs some blue hue
and on the rims there is a strong pink hue ..
those hue's are so important to get right and imo when placing parts on the car or changing colors you should match those instantly that way you wont get lost in a plallete of non matching hue's
