they are young. [excuse for not drawing angled rings since I f###ing suck]
nope. the rings of a planet are typically aligned with the planet's equator. these rings appear to not be aligned with the equator.
feels kinda weird but u can improve a bit by reading abacaxis guide(search guides by votes and click the first one)
the rings are slightly too low and bright but they're still good
maty bouta destroy your reality
the rings have very high albedo, especially for their width which looks strange also unless your system somehow has a stellar density like that of an atmosphere then shadows never really fade unless EXTREMELY far away, what i'm saying is logostevie is right it needs shadow
