This isn't a place to ask for pictures of a build. I'll give some suggestions though. For braking, I believe the agreed best right now is a wingnut braking system. See Here. As for release, think everyone kinda has their own thing.
I already have the wingnut. I was not sure what to change about my breaking system. Do you know if the method of using a pencil to hold it up through a hole in the back is accurate. I didn't know if this could be done with great accuracy, or if that was simply not achievable with this system.
I had the pencil through a hole in my ramp and a standard wingnut brake on a ~400 gram car with CD wheels, and I had regular sub-10 point runs, including at my Regional, and a sub-5 point run in practice.
Don't the rules say that it is illegal for the pencil to touch the ramp?

No.

The rules do say, however, that the competitor may not touch the ramp (5i).

Thanks, I will try to incorporate that design into mine.

According to the rules, isn't the pencil not allowed to touch the ramp?

Different approaches work for different people. Keep things simple, and do those things well. You will end up with a good score.
