Thanks @Buzzetta - Shaping the talented youth of today is always fun.
Your daughter did a great job on that Batman piece. (Also - Happy Birthday!)
My best advice to start her out with is, get her the Adobe programs - and a Mac if she doesn’t have one already. (There may be some PC fans here who will say they’re exactly the same now for less than half the price, but I still find the interface to be so much friendlier with Apple)
Anyway, I use Photoshop, Illustrator, and InDesign every day. I started out wanting to be a comic book artist, and ended up a fashion designer - I have no explanation how, but it’s a fun gig and I literally color every day like some glorified 6yr old.
If your daughter really has a passion for art, and it looks like she’s on the right track, investing in the Adobe Suite programs is a great stepping stone. And as a student, I’m pretty sure she can get the subscription for like $20 a month or something like that. There are tutorials all over YouTube to get her started - That’s still my go-to for when I don’t know how to do something. Getting the entire suite will give her access to literally have facet of the art world to see what she likes best. If you want a full list of the Adobe CC programs, lemme know.
After that, I’d suggest looking into college courses taught by industry professionals - usually they teach just for fun or to supplement income cause let’s face it, art is fun but those of us driving Lamborghinis are few and far between.
I won’t say you need a specialized art college, but if she decides to go that route, keep a steady balance of art courses and business courses (which I wish I did).
Ok, before this reply becomes a novel, I’ll quit here. I’m happy to answer any questions ya have.
