I agree that I think the soap looks fine with small wire cutter bubbles. I don't hear others discuss it but I find that my goatmilk soaps have a different soap surface look and feel; not as smooth as my soaps with water, a more rustic look and a softer feel. I just consider it a result of using frozen goatmilk rather than powder. I don't mind and if asked I think it is a selling point that it is clear I take the time to use fresh goatmilk.
You can have spots from "soap within the soap". The fat in the goatmilk can saponify with the lye and cause the lye/milk mixture to include some soap bits leaving white spots. When I first started making soap I prepared the lye/milk and then set up molds, pulled colors, finished getting oils ready. All too much time and the fat in the goatmilk would start to saponify. Changing so that I add the lye/milk mixture to the oils immediately after I have the lye incorporated and the milk has melted eliminated the spots.
