Not much progress, I´m afraid.
I thought that the fulmar-like hooked end to the beak looked good, but it was inaccurate, so had to go.

Got a little bit of "underpainting" done - structure I want to show through the final layers of paint.

Looking forward now to tedious brush-work now to "fluff" some bits up, lots and lots and lots of tiny strokes in varying tones. It´ll be done a bit at a time. Head will be most fun, starting there might re-instore some impetus.
Not forgetting some pearlescent/interference shimmer.
Not aiming for an exact likeness, but this beach-combing find will provide references :
Spike.
