I guess that the most popular question in interviews with freelance illustrators is "The best tips for aspiring artists". No wonder... that's probably the most valuable question.
Here is a list of my tips. Some of them I got before becoming a freelance illustrator. Other advices I "discovered" myself quite fast and still others were understood after wasting a lot of time and getting stuck in a blind alley:
Beginnings are usually hard, so be patient.
Be a severe reviewer of your works. Being over-enthusiastic about your achievements can only prevent you from being better.
Expand your "comfort zone", but have a specified specialization.
Don't work for free just to expand your portfolio. Personal works are much better for this purpose.
Keep the right work-life balance.
"Everything you do proves who you are".
And here's a blog entry, where I described these points more broadly especially in the context of a freelance artist grimdreamart.blogspot.com/2015…
What advices would you add? I'm really curious about them
