Here I stopped and used duplicate stitch to embroider the face faceplate (you could also knit the faceplate separately and sew it on with a small bit of stuffing underneath to make it a bubble). I outlined a 12x18 stitch rectangle with black, filled it in with grey, and then used a sparkly blue held double to make the “shine” spot.
I also knit and sewed on the backpack* at this point.
Stuff lightly so it won’t be lumpy.
