I generally don't collect other kinds of dolls. Ironically, I've never considered myself much of a 'doll person', and I don't fit a lot of clichés that are involved with being 'a doll person'. I think this is partially due to having been told as a child that I didn't play with dolls correctly and thus assuming that I must not be a doll person, but as I've grown and become more interested in art, and seen the line blur between doll as a plaything, and doll as an artistic expression of the human form, and all that entails, I've come to realise that those clichés about what a 'doll person' is like aren't particularly valid.
As far as collectible dolls go, I've only one other sort, a tiny fat faerie bjd, CoCo in 'dark tan', by Tiny Bear of Sleeping Elf Ltd. She still had the eyes and wig that she came with, though I hope to get her new ones eventually, as well as three siblings; one each to represent the four elements.
