I'm still really new to drawing and I started Fun With a Pencil a few days ago but I saw this screenshot from Kill la Kill and noticed the glasses guy in the bottom left's head is built pretty much the same way as the basic cartoon heads at the beginning of the book. His head is a rounded pill-ish shape, his cheeks are two big ovals, his chin is half a circle, etc. You can construct it exactly like Loomis says to do, just with the proportions a bit different. I know it's not exactly a cute anime girl but it's still unmistakably anime. Sorry if this is stupid or obvious to anyone, I'm just excited that I already found a way to apply this to something I like.

hi if i copy stuff from kill la kill screens and stuff do i improve at drawing more like them ?

its really fun but do i actually improve? i think i do but im not sure but its fun anyway but i want to improve
