Hello, @akwisler! Welcome to the forums. I hope you are encouraged and blessed here. 🙂 The fact that you love to draw is already a good start on your journey to illustrating children's books! Having a passion for what you do makes a difference. For posting, you could start your own blog? Or, like @Griffin mentioned, Instagram is another option! Or Facebook. Do you know why kind of posts you want to make?
@Blackpaw4 welcome! I also used to work traditionally, so that I would have an actual piece of artwork that I can hold in my hand. I started working digitally a couple years ago, because although it doesn't speed up the creation of the art, it is much easier to make edits to a digital piece. That being said, it is also very much possible to edit traditional work digitally.
I think lots of illustrators work in combination to get the benefits of both, like 'tra-digitally.' I guess I was finding that I was editing my work heavily in Photoshop, which improved my digital painting skills in the process. So it was sort of a natural transition.
With the courses, I did most of them with pencil. Also I always do my brainstorming, sketches, thumbnails in pencil first. Apart from the digital-specific courses, you will probably not feel limited or out-of-place using traditional media here.
@lisatoris I love that book! I need to read it again. It is so easy to find myself distracted by some random thing on a screen and not actually drawing or writing. Good luck! I think Digital Minimalism is another one that really has helped me. I guess I need another round with those books. 😊
@celteaart Yes, the foundation levels are great as they build on one another and even though I had studied illustration twice there are many things there that are new to me or presented in a more accessible way. So, I started with those and when i did not have time to continue watch the random demos on things like sketchbooks, using procreate, etc. Or visit a course and watch all the videos in prep for doing it properly later.
@Blitz55 Yes- I get that exactly now and that's one of the reasons I have been able to start making progress this year. Have you seen DC comic artist David Finch's videos? They are great demonstrations of how to draw the figure and body parts, he is very generous on sharing his techniques.
