**Edit, I am remixing this into a better prop for halloween. Thanks again to MustangDave , I got him flat on the build plate so there are no supports under it at all, I resculpted /added some curves and lines added some gums around his teeth, so the only supports required are some small ones in the mouth but they are easy to remove and don't interfere with the teeth, cut it out, dont pull it out. I am doing my own chestburster but it's pretty detailed (has a full body) i'm taking my time on it, but wanted one to paint in the meantime, this is working out ok so far.
