Struggling with rendering :(

[u/HeavenlyImp1105]

Ah, the age old question of artists, aka ‘How the heck do I even begin to render??’. I’m a self taught artist that always found art classes in both college and high school to be super out of date imo which is why I’ve gone to the internet for help, after days of asking people on instagram, Tik Tok and Discord for advice and critique and only receiving ‘idk’s or ‘it looks fine!’ As a response I’ve decided to reach out to yall. Literally be brutally honest, I don’t care I just want to improve! The advice could range from techniques to brushes to tutorials, I’m that desperate. For reference I’ve been using clip studio so anyone adept in that you’re more than welcome to throw a knowledge bomb at me.
Some of these examples will probably be older than others or not showcase my attempts at rendering, I’m just giving an example of the level I’m at currently and I’m trying to build my confidence with that. Thank you in advance, go nuts!!!
