Just a general question, is this FF Artwork only a change of color/material on the object or do you extrude or delete those parts to create some new geometry? Because if it’s only a change in color/material I would just use a texture for it, this keeps it waaaaay simpler.
I know this is only a small thing, but you should work as optimized as possible from the beginning on, so it comes natural when you make bigger things. This applies to mesh complexity and realization decisions (e.g. using textures instead of editing the mesh)
Besides that I would suggest having the mesh looking something like this.
Trying to keep most of the faces quads (4 vertices). I’ve marked the non-quads with the number of vertices, so you see this exists nearly out of just quads. Again this may not matter that much in this case, but for bigger projects it can cause big problems.
