The hemispheres are a nice way to tell, where the system is in a bigger context.
Some things are a bit wild for my taste. Like the names not aligning with the middle of the planets or some texts in angles.
I would also try out an alternative for the purple background in the top image.
But the style is consistent and charismatic.

Also: Perfect how you fit "The Star Garden" into that name. Or "Almaera" to "Carmenia".
