I like them as they are, myself. But for a little pizazz, I'd do a mica in oil drizzle over top for a little extra added color. I prefer that to glitter, although the younger crowd (teens, tweens & 20-somethings) might prefer glitter. But mica is probably already in your arsenal, whereas cosmetic glitter may not be.
For the honeybee mold, mica painting adds a really nice touch. It's easy and it's fun. All you need is a tiny paint brush, a small monkey dish (restaurant jargon - it's just a tiny little bowl), some alcohol or glycerin to mix with the mica and a somewhat steady hand. The steady hand is optional, but helps for fine detail painting. Paint on the detailed areas, allow to dry and take some photos. It's makes a pretty gift for mother's day, BTW.
SPowers, bubble wrap can be cut to fit and place either at the bottom of the soap mold and/or the top of the raw soap to create the honeycomb effect.
