That is really excellent. Love the winglets

Meh. Too
blocky (looks like an A330 winglet), modern Boeing winglets are more curvy.

While not as organic as later, more recent designs, even the old 747-400 winglets have a subtle curve and greater rake than
what the illustrator has drawn.

Anyhow to make it really up to date and have the Boeing
heavy look, raked tips rather than winglets would be the way to go.

P-8 raked tips similar to 767-400 raked tip design, the first of the raked tip Boeing aircraft.
