A piece of constructive criticism on the original post.

While this is a pretty neat design, I would recommend add in some hoped objectives. Some years this is a bigger deal than others. This year it is especially important. Statements like "tunnel only" or "planning on going over the bump" will help critics out immensely. Essentially you are asking for a design review. Without knowing your objectives, it is tough to give valuable criticism.
