So I've been plotting a streaming (re)debut for a while now, moving from using a webcam to vtubing/PNGtubing.¹ I drew a lot when I was younger, so I'm planning on drawing my own avatar (HEAVILY based off lil Baby Sesame!) - however, there are two big issues here.

1. I am absurdly rusty. I can get past that.
2. I have zero experience working with digital art.

So, any suggestions folks? I got my partner's iPad and a cheapo stylus I picked up, so no pressure sensitivity for me. Any guides or free/cheap software? Was gonna use an app to make it but I'm pretty unsatisfied with the results so I'm gonna move to doing it on PC, get myself a bit more control.

Lineup of my characters.

Marcelle, Yvette, Cori, Kain
