/ic/ - Artwork/Critique

When will I know I’m ready to quit my job and go full-time on art?
What are good indicators: having a lot of clients lined up, matching your own standards in your art, making a lot of money per commission, making a good hourly rate based on your own workflow?
The only reason I’d entertain it is because I have a lot of clients lined up. By my own standards I’m not that good, but it’s also hard to practice getting better because good practice cuts into my actual drawing time, which nowadays all goes to my clients. They’re starting to get frustrated that I’m not getting through my queue fast enough. Mix of animation and illustration clients. They won’t say as much but I can feel it.
My main animation client is constantly giving me work and the work I’ve been doing basically spiraled into pre-production for an animated film(I’ve been paid all along the way).
Aside from that guy, I have 3 other people who want me to do some work for them. 2 of them are always in my backyard asking me to do stuff, long-term work on things like comics, animation, etc.
My main bottleneck to getting more work done is time management and the amount of time I have to work with. My average is 2 hours of drawing per day, 5 hours when I have the whole day to myself and I haven’t been exhausted by my dayjob(cafe).
