Cool!

The only thing that spoils the attention to detail for me is Saturn's rings - their inclination is not that high! Also, if you're including named KBOs, Ceres' and Pallas' absence from the main belt is conspicuous. You could also include the Jupiter Trojans and some prominent comets, but that would of course add to all the data you're already including.

Stylistically, the only things that stick out to me are that the "portolan" lines might look better if they were a darker gray, and I think I might like the asteroid and Kuiper belts better if they were represented as more stylized bands than with dots. (Yes, I know, this is an ironic comment given my current project!)

Don't worry, I'm nitpicking this because I like it a lot. It reminds me of the Tabletop Whale solar system map, in a really good way! Thanks for sharing and I'm looking forward to more!
