It seems like on all the obvious pages like Deviantart or Instagram, your success depends on MOSTLY how much exposure you get by commenting or following other people, rather than how good you really are. This seems fair at first but then you see that people will follow you just so they get a follow back etc. I understand that, but for me it is pretty hard to follow people who have shitty art just for the sake of exposure.
I don't know a place that judges purely based on quality rather than having to follow ppl around to get noticed.
Artstation?
