There's a lot I can help out with and most likely they would be video based but...
What you should do is give us a photo or artist or artstyle you want to achieve....it'll be easier to help out with
for instance I learned to draw from manga. Manga has so much line art, perspective, poses ect. in one book and it's could potentially be from your favorite artist......
I learned to draw by studying manga from the manga NEGIMA by Ken Akamatsu
So I had a goal to be as good as him.....and while I was learning from the comics I was looking at other artists....maybe I like how tetsuya nomura does eyes, or how Anthony jones paints form and light or how Tobias Kwan paints arms....but I had images and I knew what I wanted to achieve
While I was at my beginning stages of learning I didn't stop to learn anatomy or color ect.
I really didn't worry for that...all I worried about was the "art of drawing"
So if you can potentially show me what you want to accomplish it'll be easier to help out with
