Creative. I'd make the base a little thinner so it lays flatter on the barrel. And that one narrow decorative slot across the front extension might create a sharp edge to catch clothing, hands, etc. I'd lose the sharp edge. I'd lose all sharp edges.
As others stated, maybe you chose brass because it's different, but you'll need to tarnish it to be able to see the front sight in the notch.
Also, another topic is that most sights nowadays are about twice as tall as on originals. We got used to big old tall open sights on our .22 rifles or Winchester 94's and never got over it, I guess.
