that bezel honestly looks a bit small to fit top mount '
i suggest at least making top and bottom bezel uniform . you don't need to make all sides, just top and bottom, because right now it looks weird with asymmetrical bezels ~
and you will want to chamfer the part next to the knob so it's the same as the other sides
Other than that, I think it will look quite cool once finalized.
Colors: silver and black should be good for almost everyone, you can add a special color if you really want.
