Agree with guslaw -- Poser 4 or DAZ Studio. You want to be concentrating on the painting and drawing: Poser5+ and the whole Mil Figure thing will just suck you into playing with Poser, struggling to get better renders, buying new figures and textures... But one caveat. If it were easier to use, dynamic cloth would be a lot better to work with in getting the basic drapery folds in. With conformers, you are stuck with only those folds the clothing creator built in -- and they do not naturally follow body shape or movement.
