no idea if this'll help since your attention span is running low but you can't have that if you trynna learn digital art
1st: Drawing head, sharpen your skills in drawing head from different angles front, back, quarter-view, sideview or not dunno, look through YT I recommend Marc Brunet or mikeymegamega
2nd: Draw eyes and noses, there are different types so find one that floats your boat then improve the way you draw it. Try applying it on the head if it fits or not, if it doesn't better luck next time and if it does congrats, ig?
3rd: Body anatomy, find a solid body anatomy that you can work with or make your own, trying drawing random shapes from different perspectives it's up to you. After having your own body anatomy, try finding poses as references to draw, I recommend this website:
https://quickposes.com/en/gestures/random.
4th: Good luck drawing hands, https://www.youtube.com/watch?v=1FDrizAhPa8 and the feets are kind easy Ig?? as long as you know how to draw a triangle. Prolly.
No idea if this is what you meant, but it'll prolly come in handy and I have never gotten to the coloring part since I always drew on paper. Best of luck to you
