Oh I love drawing. First off, you don't need tutorials. I say this because no one can really teach You how to draw. Sure, they can teach you basics, like anatomy and proportions. But learning yourself opens so many windows. You find your own style and it can become truly unique and part of you.
So what I do is visualise.
With a blank piece of paper, shut your eyes and think hard of what you want to see on the page. Do this frequently and you'll see outlines in your mind that just don't exist in real life. The skill is transferring this to paper.
Your first attempts might be poor. But you will eventually get into the hang of visualising what you want to see, and bit by bit your skill at transferring it to paper will be achieved.
