First of all I'll ask
How do you want to make money?
- With commissions?
- Making comics?
- Making designs for platforms such as RedBubble or similar?
- Making merch?
Second, "From the millions of artists that post their work on a daily basis, what can you offer? Why would someone pick you from other people?"
Now, this is a question I used to ask myself back when I started but while It is not mean to put you down, it is to be realistic. You have to consider your own abilities, you have to be honest and sadly, if you're trying to put a price to your skills, then you'll have to compare yourself to other people on a similar level as you. While it is true that anyone can put any price they consider worthy, at the same time it is a lie, you have to check out the prices used on different places, based on demand, abilities, availability and such, because at the end of the day, you want clients, you don't want to scare them away or to ridicule you (which happens a lot with amateur/novice artists who jump right away to do commissions)
Personally speaking, without a fanbase, there isn't much you can do. Especially when you're either new to art, new to social media or simply new to selling your art. I always calculate, that less than 5% of your following will be willing to actually support you.
(I'll be honest here, so I apologize in advice something I say is not of your liking)
As well, looking at your Instagram, which is basically like a portfolio, I would recommend first to enhance your abilities, as there are several errors in anatomy, proportions, coloring technique, etc. I also see that your art is not consistent enough and despite you make errors on the same places, sometimes it's a bit better and sometimes it's a bit worse. If I were someone looking to commission an artist, I would avoid playing "Russian Roulette" since I won't know if I'll be getting something somewhat close to the samples that were offered to me, or something that ends up being... not as great. And it won't matter if you offered wips or allowed corrections in certain steps of the work, it'll still be inconsistent since you don't seem to have found a style yet, I can tell you're doing an effort of mimicking other's styles but there is only a certain amount of things you'll be able to replicate.
As well that, since you're a minor, I wouldn't commission or hire you (But this is more a matter of personal choice, because I don't like working with underage people independently if what I were to commission is completely suitable for all ages. And this is something that happens with several people in the commission field, so... yeah)
