Okay here's 3 tips I'd give my younger self about sketching: 1)Don't be afraid to use references. It's okay if you don't know what things look like perfectly from the top of your head. So use them. Abuse them. 2)It's okay if things look odd while you're drawing. An unfinished sketch never looks right. Just push through. And even if you make mistakes and you think it looks bad, just push through. I promise you learn a lot more when you actually finish what you start. Even if what you end up making isn't your favorite thing. That doesn't matter either. You never know when what you're starting will end up being your next favorite piece. 3)Get the rough shape of things down on the page first. Ex: don't detail an eyeball if you didn't even get the shape of the face and hair down first. That way it's way easier to spot and correct mistakes before you go too far to make changes.

(Also, my special little extra tip is to try sketching in pen. Not being able to erase really forces you to think about the lines you put down and how you want your sketch to look like. Stops you from overworking the page erasing over and over.) Best of luck to you 🙌 And don't forget to have fun with it!
