This is where I am at right now too. Seriously. I started learning Graphic design in 2002 at a community college, but I still had more love of drawing characters. Then I studied Graphic Design again at an art college from 2005 to 2007. I had a few animation classes, but I couldn't get my head around the programs even though I got A's. I've never felt Graphic Design was for me, and I kick myself every time I think that I should have studied more Illustration. My husband and I recently moved to the other side of the state (MI) since he got a new job. So I am trying to take this time applying to illustration jobs and working on my portfolio.
I'd say check out some of these videos at SVS:
• How to Perfect Your Children's Book Portfolio
• Visual Story Telling Techniques
• How to get Freelance Work
When you're portfolio is ready the best to do is send out postcards of your work to publishers. You can get the publishers addresses from this book "Children's Writer's & Illustrator's Market 2017" on amazon or your local Barnes and Noble. (I still need to do this lol! But I don't feel ready...) Also, you could join https://www.scbwi.org/ and go to local meetings in your state.
mallettedesign.com I have both my illustration and graphic design work on my website, but I think I want to get rid of it all together and start over with just my full name . com and have illustration be the focus. Anyway, Good luck! I'll follow you on instagram! :D
