This is an exceedingly good drawing - a new major talent has arrived
Re the funnel shading; I'm not sure I grok all the new rules myself; but I would prefer the shading that indicates the curve to also reflect the direction of the light, always coming from the bows; thus a lighter shade on the front, then the proper shade on the middle, and a darker shade on the rear section; but not too much of a variation on these, as it looks better done like this.
