I'll add that frankly, I do not enjoy drawing pictures "of things." I didn't really enjoy drawing that Morgan Freeman, simply because I had to stare at a picture for hours on hours just to get his teeth to look decent. I much prefer to draw images from my mind, as it is based more on interpretation rather than style, hence why I enjoyed drawing Bob Marley. Is it perfect? Absolutely not, but it's how I saw him in my head, so I drew him that way.
