I am with Nicole here and I am not answering your question whether to go for it or not.....maybe I am not brave enough after the debacle in the other thread.
Having said that.....I haven't seen a goddess tutorial that looks like your goddess. I have got Kate Fowle Meleney's book (The Enamel and Electroform Decorated Beads) and Lavender Creek's tutorial and their goddesses (in their tutorials) are almost identical.
