maybe an unpopular opinion but I miss flat animation art in movies. Hunchback, Prince of Egypt, Land Before Time, The Iron Giant, Treasure Planet. maybe it's just bec I'm a 90s kid but there's just Something About It
okay sticking the rest of my explanation under the cut because it's long but woooo mini-tutorial for cartoony teeth by someone who doesn't know how to explain things hope you're ready
things that i was too lazy add in but i think are still important:
NEVER be afraid to use references... if you can't figure out what you want, and googling stuff doesn't help, you can even go make faces at yourself in a mirror for a minute.
if you're not drawing in a realistic style, know when to add detail and know when to skip it. you don't usually need to outline each individual tooth unless the focus is on the mouth itself or you're going for a creepy effect... see the uncanny comment in the first slide
okay that's it uhhhh remember i'm not a professional? i just draw silly guys for fun don't take this as law or anything!!! have fun with it!!
I love and stand by the idea that Luigi is a little menace. Like when you first meet him he's all shy and sweet but once you get to know him he's actually a little demon who likes to annoy and bug Mario and mess with his friends.(Him and Daisy are in a forever lasting prank war and sometimes they purposely plan it so Mario gets caught in the cross fire)
I like to imagine that if the Darklands and the Mushroom Kingdom finally settled on a peace treaty this would be Bowser and Luigi's first genuine interaction without fighting.
It wasn't the answer he was expecting but now he's curious and intrigued by the Green Mario.
