Mickey,
Not bad. But I think the proportions are slightly off.
Maybe a little longer. No pop rivets or spot welds. Maybe polished aluminum or brushed. Holes or louvers on the sides?
I'd look at some vintage airplanes for inspiration.
The other route would be like Merklin does - Square rubber boot with a stainless square ring at the base, like you find in the old muscle cars.
If you're going to leave the brake lever where it is you gotta go with one like Corey's - Spyder style.
I like the direction you're going.
