Wow, your work is incredible!!!! So inspiring as someone who is trying to get better and hope one day publish a comic series as well. Amazing how good you were at a young age. Definitely born with talent. Keep up the great work!!!
Sorry if this has been answered already by other means - but she did put an explanation of sorts of how she did the comic pages for A Redtails Dream, and she has made a walk through for Stand Still Stay Silent Book 1.
For aRTD, she basically traditionally sketched and inked the pages, scanned them, and colored it and such in Photoshop. Later on, she switched from a regular drawing tablet to an on-screen one, so things went faster. For SSSS, we'll have to see when we get the books. (Or you can see the PDF if you already have it from backerkit) But SSSS is completely digital now.
