It's really all of the above, as generally one leads to another. It's a great way to learn new techniques. For me I see something on dA that makes me go damn I'm not pushing myself enough and try to learn new ways of coloring/drawing/creating pieces. For instance I really didn't consider creating something totally in vector until I started following more of your work Shar. Thanks to all the tuts you've put out there it really piqued my interest in that artform.
