I don't do this sort of piercing because it just doesn't suit my style of turning (it is too time consuming and delicate for me), and this is where this piece has problems. The overall effect is fine and the patterns that you've pierced are great (remind me of runes), but the fluffy residue suggests a blunt cutter, whilst the frequent over-run of the piercing, beyond the boundary lines of the pierced panel, suggest that it was a bit rushed.
