I need to learn how to draw
To be able to draw something challenging for you you have to learn how to do the basics first before you do anything else. Also drawing is a skill as well and some people that has that skill of art can help others that wants to learn how they did that. For art it's not about painting, and a pencil, there are other different tools that you can use as well to make art. You can use different materials to make art as well and if you want I can give you pointers on how to do some basic things like 3D sketching, and other stuff.
