There's really no need for the sarcastic here.... You could've said something useful, like how can I improve this or something
Then don't be sarcastic yourself too.
Asking 15$-35$ for something like that is hilarious by itself already.
For that price i could get a print of your avatar,or even a shirt of it.
But since you'll just pretend i'm just making fun out of you and nothing else,then here's my suggestion:
First,don't even think about raising money until you're really good at making art. You'll know when you're good enough,but for sure not now at all.
Second,never start projects you have no idea how to start and maintain. If you don't know how to make a "poke-art shop" and if you don't know how to make fine art,it's not gonna work at all.
So what should you do now? Improve. Keep making art with the mindset of gaining nothing but drawing capabilities.
You might want to take requests for example,everybody loves them and they allow newcomers to train.
Somewhere getting abused because of my skin color.
I don't think the work is that bad.
I would consider maybe printing the art on canvas, or posters then sell them at that price like the above site.
No one would buy the art "as is" considering what you posted.
Hope that gives you some better insight on how to go about doing so.
