I already made a post once asking people what my art would be worth, but since that was already a while ago and I've improved a little since then (I think?), I'd like to know what people would pay for my current art and whether anyone would be interested at all, lol.

I'm still not sure if I'm actually going to open an art shop soon, due to having to study a lot, but I am planning to do it in the future.
For now, I'd be able to draw Chibis, Fullbodies, Headshots and Pixels (150x150, 200x200, etc. etc.). I have to add that I'm not that good at backgrounds yet (or at least I'm not exactly a fan of them, lmao).

Anyway, here are some examples of my recent art:
(not very recent actually, but I still like it)

(My current icon ^^")


(was planning to make this one a YCH, but I wasn't sure lmao, therefore the plain color)
(this one is very detailed + has a background, took me at least a few hours)

So what should I charge for my art in case I open an art shop? I don't really want to go too low though, since I do put a lot of effort into my art.
I'm also open for criticism, as long as you're not too harsh. ^^"
