Well, I’d recommend just DRAWING anything you love and are interested in and Study from life itself to start off. Drawing isn’t like something you learn inside-out step by step, it’s something you get better at the more you put it into practice. Study and the Basic Fundamentals are generally key to learning about and analysing when you’re looking into any area, but I really recommend you put in the research and find what it is you’re interested in.
I mostly recommend using life reference and practice different techniques to find whats right for you. I don’t have a source of “Guaranteed Books that’ll teach you how to draw”, You’ll just need to put in the mileage and effort.
I could recommend Vilppu and Loomis like everyone else and tell you to check out Life/Gesture drawing videos to get an idea of the techniques that come into method when drawing.
This could help and it has tonnes of reference and blogs you can check out.
Don’t expect it to be an easy ride, Keep your head up and keep doing what you love. You may feel compelled to compare yourself to others, but you should honestly work on your own strengths and iron out your own flaws. You’ll find yourself surpassing your own favourite artists in your own area. Even crazy amazing artists have areas they have trouble with, it’s all about understanding you have trouble in that area and working to fix it.
Mileage. Thats the Key word. You WILL now and then reach a plateau, you WILL get blocks, you WILL feel envy for your peers, but don’t let that stop you from wanting to grow.
For Animation, I do recommend checking out "The animators survival kit" and “Disney Illusion of Life”
