Oh, that was one of the mistakes I did. Post too many Fanarts and then whine that my followers only like the fanarts and not my original work 
I had to start over again, only concentrating on my original work in order to correct that circumstances...it worked out pretty well tho 
But on a related note, I dislike it when artists put down other artist for only creating fanart. Claiming that fanart artists only draw to seek attention and 'fame' while only original artists are the ones making art out of love and dedication. Therefore only they are 'real' artists...
Honestly...nobody has the right to decide who is and who isn't a 'real' artist.
You pick up a pencil and draw, you're an artist. Doesn't matter what or why you draw. The rest is up to you 
@topic
Also, I dislike how some artists rip openly on other's Patreon, Ko-Fi or other fundraising accounts/methods. Claiming they are 'selling out' or such...
Once again, it's up to everyone themselves if they draw as a hobby for free or if they seek to get a side income or even make a living from it.
Nobody has the right to judge over it. Besides it doesn't influence anyone's life if ArtistX is making money from his work or not (well, except ArtistX of course XD). So why do people even bother bitching about that? Use your time and energy creating art instead, for goodness sake!
