/ic/ - Artwork/Critique

Hello, everyone!

I have some questions about the illustration business in general.

I know the competition is HUGE because every illustrator in the world can work from home and etc but I want to pursue this carreer.

First question is, how can my work gain more visibility? I mean, I have IG, Artstation and deviantart pages but there are not many followers, I even tried to phisically spread business cards with my pages but didn't result in many traffic.

Second question, how usually does companies pay for the gigs, in a big sum of money or spread, is there even royalties? I mean companies like blizzard, riot games, epic, WOTC and etc (not like my illustrations are even close to be that good but that's my goal)

How many hours of study do you guys usually put daily?

thank you in advance

PS: i'm sorry if i made any grammatical mistake, english is not my first language.
