Finding tip videos for my art proj

So I'm really stressing for my school art project this year. I'm in 6th year, or 12th grade, anything you'd call last year of school T^T

And i plan on using gouache, something I've never used before..

Also if anyone is wondering, I'm drawing my own oc for the final project ^^

I decided to find a bunch of fun videos on how to do anything with gouache! I wanted to put them here, because why not, maybe someone will see it and like it :]

I AM SO TIRED!!
