I love to draw but I am not good at it. My visual art skills are totally in appreciation versus execution
Is all drawing the same, or are there different types? 
There is art drawing and technical drawing 
what is the difference? 
Technical drawing, drafting, is drawings that communicates how something functions
Oh, that doesn't sound very fun. What about art drawing, what is that all about?
Art drawing emcompasses commerical illustration, animation and just fun
