most great designs can be overcome by creative sculptors! have fun with the designs and I recommend not to limit yourself. Undercuts & negative draft are realities though - don't do designs where the molds can't be pulled off at a 90 degree angle off of the sides (for example, a nose where the tip of the nose has an area underneath it where it recesses upwards... think about it in 90 degree pull terms).

You answered before I could! But I'd like to add that, although fewer mold parts makes it easier and the molds cast longer, you can have an infinite number of undercuts. Just depends on how much work you want to put into it. I have one mold I made which has 6 plugs inside the main mold parts. Of course, it's showing some pretty serious wear these days....
