I,m not trying to come off like a lead balloon but I don't think that is a good type of harness for a bully . I have a feeling Bruno and you may have some issues with it in the future.
Let me explain.
I work with leather be it for clothing, knife cases , guitar/bass straps etc.
The tooling on your bully's harness is beautiful but I don't think it is functional or going to be comfortable for him for long.
That harness on Bruno is made of a heavy harness leather. Its more suitable for saddlery , just too thick for a dog harness, It is going to absorb a lot of sweat and moisture and start rubbing on your bully and may well start hot spots and bald spots.
There are three large metal buckles IMO they are just much too large, and the harness maker could have went with something much smaller. I prefer to use those snaps as you find on collars, they cut down on weight and much easier and functional on a harness.
IMO had I made that harness I would have spent a bit more time on design and used a lighter weight of tooling leather and padded the harness and not used the huge buckles. it just makes the whole appearance of that harness look to uncomfortable.
