I am not sure it can be done, in which case it seems to me that the 'it factor' is just drawing fully rendered, highly detailed art with background elements. . .
Obviously some variations exist, arguably one wouldn't consider Katie Cook's work to be highly detailed, but it hits the other marks.
I will try it later today. That kind of study will need to take into account the celebrity factor, the scarcity of the particular artist, and the timing of their entrance into the field.
