Hi! Gather your influences + improve your life drawing. A good way to start is by finding good illustrators you want to emulate. When I started really getting into drawing, I was obsessed with the work of artists like Jillian Tamaki and Kali Ciesemier. I decided I wanted to draw more like they did, so I studied their techniques, and once I did that, I put them into practice! From there, I got a sketchbook and sketched actual people (from life or pictures) to practice anatomy/shading/etc, while trying to apply the techniques I learned at the same time. I'm still doing this up to now and trying to get better, but since I started I can say my drawings definitely look WAY nicer than they did before. Think of sketching as exercise: you never stop but you get better and better as you go along :)
