Summary

I printed the blank minifig and it looks kinda boring without the eyes and mouth. So, I printed the remix of the head with eyes and mouth cut out but something was still missing.

Print these eyes and mouth, I suggest going for the black color, and they should fit right into the holes in the head and make your minifig look a lot better!

Post-Printing

Use a knife or similar to cut of imperfections in the eye and mouth holes on the head and on the eyes and mouth.
Pop the pieces into the head, make sure they fit correctly and are flush with the surface of the face.
Sand the entire face together with the eyes and mouth in order to create a smooth surface and make it look (almost) like everything was printed as a single piece :)
