boy 3

I like the drawing. I'm a complete novice and I just wanted to ask if you could describe what materials you use? And the process by which you draw? I mean do you use softer pencils starting off and then thicker pencils when adding detail? Or is it the opposite. I can never seem to get the detail I see other people getting in their drawings. I am using a 3b since thats all I have laying around at the moment. Any suggestions on how to get more detail and the process? Thanks.
