For beginners, do the easy stuff first.
That means getting the basics right.
You can learn a lot from "How to draw" books.
Don't go for style yet. You have to know the rules before you can bend them.
I see some people dismiss proper anatomy, perspective and all the laws and rules about art, by saying it's his style.
Always draw. Draw everything and anything. Keep drawing.
Here's what I did.
1. I always drew when I was younger and I still try to find time to draw and paint when I have time.
2. Everytime you do, you keep improving. Researchers have shown that if you can chalk up 10,000 hours of practice, you can achieve expert level in skills.
3. I attended some art classes.
4. I bought self help drawing and painting books.
5. I experimented myself on drawing and painting techniques.
6. I copied. I loved to mimic and see if I could duplicate what I see exactly. Whether it is someone's pencil drawing, my favourite comic book cover, a painting or poster. I tried to replicate it. When I do, I am also learning and practising. I get accustomed to the shape and flow of the subject I replicate. I learn.
There is no real easy part of the body to draw first if you ask me. I always start with the stick figure skeletal outlay of the figure first and then flesh it out.
But if I'm drawing a female character, after I have the torso laid out first(without details), then I like to do up the face first. It feels motivating to look at a pretty face while I finish up the rest of her.
