I say finish it man. Looks good as it sits now so why not see it all the way through. If I man make 2 suggestions:
1. The blue I believe should be a slight bit darker.
2. Give the blue and the red more of a v shape like in the pic of the movie car. Notice the red is pulled back to just about the a pillar and the blue is pulled back behind the front wheel openings.
Looking good so far so I say wrap it up man. Love the primered deck lid. Thats one thing I always left out on the cars I have done with this scheme.
