i think you should flow from just below the upper grill the body line follow that up onto the hood across paint the top of the hood black and then trunk black basically a thick black strip across the hood.
now i can do alot better than this, but i'm on my laptop right now and using that stupid lil touchpad lol. if i had a mouse it'd be alot smoother but this gives you the idea i am talking about.
Looks good,IDK how you do that in PS, but there needs to be a transition between the two, a pinstripe or something. oh and black and red are over done.
I agree about the pinstripe...what other color would look good i'm open to suggestion cuz yea red n black are played out I just thought it would look cool havin the top blacked out since my windows are so dark
