Looks good, those chrome fenders are sharp. Makes me rethink putting fenders back on my bike. But you will want to see about reinforcing the fender mounts or if they break they can get caught in the wheels and pitch you.
I never had a front fender on mine since the stock one would not work out of the box with my front springer, but I had a rear fender on my Cranbrook that lasted about 100 miles before the bottom and middle mounts both broke. I caught it before anything bad happened and off to the scrap pile it went.
Also, you ground a LOT off the cantilever. I know they tend to break farther back near the seat post so hopefully there are not big loads on it where you cut...
