I have not yet explored this - but - I think the "rest" machining strategy would be a good fit to do a project like this. This is where you would use all the normal tooling, like a 1/4 ball nose to rough 3D, and a 1/4 flat end mill to do some pocketing, then a 1/8 taper ball nose for the rosette and possible the frame profile. The rest machining would get into the corners and tiny details with a v-bit - maybe 60 degree.
It's a nicely challenging project.
