Hi there!!!
Gonna try to help the best I can!
First: Digital or traditional?
-It doesn't matter. Both are mostly the same as you are the one who do the drawing. Its good to have technique, and that comes with practice, and you can practice in both at the same time, there is no worries! Digital has the advantage that you don't need paper or pencils, BUT you need to buy equipment that can be pricey. Also the ctrl+z can become a crutch if you only do digital. Traditional is cheaper, but you always need more materials, as paper run out, but builds confidence in your linework that digital can't compare to.
But.. .what is technique??
That depends on what are your goals. If you want to learn Powerpuff Girls style, go for it! BUT, on my experience is the best to learn the basic anatomy, and later go into manga/comic/antro/whatever style -because once you learn how everything is connected, you can deconstruct everything at your own leisure.
How to learn basic anatomy? - First, the head- Loomis Method vs Reilly Method.
Here you need to search wich method is better suited to yourself. Maybe there are others methods, or even a mix of those will be enough for you. Don't let yourself fit in a box if you don't want to!
...and for the body? - There is a lot to learn about the body, such as how many heads taller a body can be, the proportions, muscles, bones, expression, etc, so you gonna need to search for tutorials, be it on YouTube, paid pages, books, etc. There is a lot of sources, and all are okay. You can start doing a stick figure, or a 3D block to see the body, or try life drawing, whichever is the way you choose, in my opinion all of them complementes each other, so go to all you want and learn.
And after the body? - You still need to fill backgrounds!! So you will need to learn about...
Color. - Values, tones, hues, light, reflection,
Composition - Focus point, vanishing point, linear objects, overlaping figures, general value changes, graphic reading of light and dark objects, contrast of shapes to have foreground, midground and background.
Narrative - You have different types of narratives, like monoscenic, simultaneus, continuous, sequential, synoptic, panoramic and progressive.
...is that all? NO! Because between all that you will need to learn about clothing, fashion, arquitecture, interior design, graphic design, lettering, paneling, and script!!
That is all I can think of the top of my head.
Its scary, but you are not the first person who try to draw, so don't be afraid and grab a pencil and start drawing!
Good luck!
