Seriously mate, nout wrong with your work there from what I can see and it serves it's intended purpose, top work.
I suggest making a track bike from the curvy, sell the fairing and put track fairing on it
One thing to be careful of with nailing the felt down, it's normally where the leaks / problems start.
Just keep an eye out for any curling up of the felt cos once water gets in it will rot that in no time.
