I'm having such a blast this year creating custom cake toppers for my clients:) I LOVE to sculpt! Typically I use Sculpey clay and then hand paint them once I've baked it all. The result is a lightweight cute and quirky memento from your wedding day!
My toppers are simple-- no realistic faces, nor tiny fingernails... honestly those toppers that look just like you kinda freak me out.
(this one I love... I get to see it every day and it reminds me of how very lucky I am!)
