I see...
The high price of art supplies really put me off from learning it.
I am very financial conscious, so.

I didn't join any of those sites... so I don't know how it works.
But the fact that you need 'fanart' to gain attention means that, the audience is not your target customer.
Real interested customer would be attracted to your art for what it is, not because of fan art.
I do think that you need to go elsewhere to find prospective customer.

Spring art and craft sounds like a good one. *nods*
At my place, the art were mostly obtain through gallery or artshops, as in physical ones. Very seldom to buy from online.
