See if I was advising my high school students, here’s the advice I’d give: yes being paid for your work is an awesome feeling and you should never work for “experience”…I’d also say you will do better work if you specialize and try to focus on a field you like. For instance, I don’t care how much I’d get paid (and from what I’ve seen it’d be a lot), I will most likely NEVER illustrate erotic art. Yes it’s illustration, yes it’s freelance work and paid, but because of personal beliefs it’s something I’ll never do. On a somewhat similar note I have never felt to drawing illustrations for board books for kids.
If I remember correctly based on what I’ve seen of you around the forum, you’re either in high school or just out of it, is that correct? So my advice (and others can weigh in on this), I would concentrate more on building your portfolio and doing work that excites you…that will point you in a better direction.
I absolutely agree with Will, Jake, and Lee, there are going to be times where you take anything you can get, I just worry you might be jumping too far into that in such a short time? Again, if you want to go into educational work that’s one thing, but try exploring the other markets as well!
