STEP 1 - Choose something to say. I wanted to say "projection" or freedom in this one. So, I took my hand, the closest thing to me and drew it tossing something over the sea. The sea has always been the freest place to me.
STEP 2 - Press graphite to paper. Observe your subject. In this case, the subject is my hand. You can refer to pictures. I've drawn the sea enough times to skip referencing a picture. If I decide to paint my sketch, I would refer to a photo or an actual body of water. Closer to the reality the better. Use the real sea if you could.
STEP 3 - Erase and refine your final drawing. Just don't overdo it. Beginner's have a tendency to overwork stuff. As a rule, you are usually done before you think about going back and making everything better. Stop, before you get too far ahead. You don't want to lose the humanity that already exist in the work. Some advice, when you look for perfection what you're really looking for is a machine to do it for you. If you want a machine to do what you're doing, it just means you're not really enjoying what you're doing. Slow down and enjoy art. The product is great to have, but enjoying the time and exploration to get there is really the joy. You're never going to be finished doing art.
