My thoughts regarding the raster style tools have been related to my general lack of artistic talent. I tend to have an analytic thought process and more than a little bit of a perfectionist streak. Those personality traits would not seem to lend themselves to a free-hand style of tool as much as a tool more oriented toward placing established icons at appropriate locations. But maybe I have misread the little I know of PS and Gimp (and CC, for that matter). I would welcome feedback in this regard.
