Be nice to find some Allen~bolts to fix the tops on with, rounded top ones or drill an insert so they're flush with the surface...
I'd like to see the tops cut down a bit, have the holes come out in a curve by themselves...

Kinda thing but with some nice curves...~~
Laquer has to be put on VERY thinly, otherwise it'll run all over the place!, might help to keep the Copper warm before you spray it
...
Nice work though, keep it up!...
