Great job so far! I like this style and have plans to build my own. You should see my take on this theme, along with a couple others, coming soon. I am interested to see yours progress. I started with the crappy pink one, so anything will be an improvement.
I would say keep the door lines going all the way to the bottom, and if you are going suicide, try looking at the older versions that have the side vents. I think having both of those opening the same will look good.
Looks great. Like the color combo. The only suggestion I have is it looks like you have a left and right side wheel on the same side. They are directional wheels so the spokes should point the same way. Everything looks good. You may try to mount the stock tail lights under the car, on the frame rails. Just a thought.
