Make the cab for yourself, and your needs, not for the validation of others.
If your cab ends up in here, great, you did an exceptional job and had processes and techniques that should be examples to others. At the same time, your cab's theme was well executed, and is one that people would love to own for themselves.
But the bottom line is, promoting your own to get into the HTF is kinda low. If people think your project is exceptional, it'd be in here.
