a number of notes:
1. the time estimates were done with backgrounds in particular in mind since i'd be doing them more; you can generally just divide the estimate in time for the amount of time spent on character portraits
2. the time estimates are estimates of total time, not counting in time not spent working on them. i'll generally do works in sittings of an hour or two, and i'll usually have the time for at most two sittings of work in one day.
3. if a black and white style is chosen, i'll probably have to change the look of the so-called "GUI" to fit, but, hell, we'll cross that bridge if we ever get there
