Doodles in The Foxtail Community

I'm trying to practice with, like, drawing stuff so it looks 3d but I'm getting so bummed out doing it, so many lines that don't make sense to me

Tried to draw a character, in a fnaf typa way, and it turned out looking trash so I'm scrapping the idea all together.

Found an old drawing of my cat anatomy, maybe I'll use it, idk. (This is from 12/14/24 )

doodles cause I got bored listening about how the combustion formula always need fuel, O2 that creates the product of H2O, CO2, and energy (And then proceeding to do tables on something I just learned that wanted me to find the molar mass of them T~T)

I only asked the way to the bathroom T~T
