Happy/cute dolls are usually cartoony, and include themes such as fairies, flowers, glitter, rainbows, etc. Unfortunately, I’ve realised that a lot of the cute dolls don’t have much depth or context. They focus too much on looking cute, and less on having meaning. I have to say that a lot of the more popular dollers find their style to be like this, but a good doll without meaning is shit, whereas a badly-done doll with concept and originality is awesome.
The same can be said for darker dollers and their use of blood, gore and sex. It really depends on how much you look past the OMG SHINY and focus on what matters: the idea.
