Komurasaki’s nameplate is finished!

I finished the Komurasaki nameplate. It looks pretty good, don’t you think? I wanted to attach it to the gate right away, but I need to drill a hole in the concrete wall. The nameplate is too heavy, and there is a risk that it will fall off if I use glue. So, I need to drill a hole in the wall and secure it with a bracket. I’m going to buy an electric tool soon and try to drill a hole. I wonder if it’s okay for me, an amateur, to do it?
