Chibi Chrysler ME Four-Twelve

I kinda feel like I butchered this one : / Not many pics of the car that I could find so it was a bit of guess work. I'm starting to think that there are certain cars that just can't be chibified. It came out a lot better than the sketch did which I later realized was seriously flawed. I'm realising that there isn't one way that works for shading these cars. What might work for one doesn't work for the next and so I can chalk this one up to a little experimentation.
