Further additions:
Other style themes worth investigating:
1) Tick-stylised.
2) Hyperbolic lines.
3) feature line cross.
4) intersecting solids-used on ZZR 1200
5) thick/thin swoopy "Z".
Alignment with "built-in" features and edges.
Try to carry style-alignment details across the fairing as well.
I don't need profile continuity curves- the ducktail aligns with the rising side feature.
The "Airbox Tank" section doesn't need to be teardrop-shaped.
A lot of it is concealed by the fairing.
Maybe the shape needs more integration with the fairing- hollow curves connecting them?
The ability to seperate airbox-tank and fairing is useful for construction.
Concealed parts can just be shaped by utility.
The fairing rear edge is determined by rider knee clearance and toe clearance,
but can be more curved in side view.
