Knowledge Is Power and you draw a very beautiful drawing and relates your drawing to knowledge power that how are pen is destroying the gun which is not the sign of peace but it's very unfortunate that after a lot of hard work you miss to share the step by step pictures with us but no worries next time you would remember it.

It seems in your drawing a one mistake that I can see that you are not holding the pencil fully in your palm and your pencil is behind your palm and it's a major mistake that everyone can see and over all I like your drawing.

Specially the grey or the blackish shade that you give your drawing is looking gorgeous and really stunning and I am hopeful that next time you would express your talent professionally....
