Give examples from books
I like a lot of different character types, but I quite like strong female leads with a bit of humour thrown in. Blaze Halfbreed from Glenda Larke's Isle of Glory novels is one example. I don't like it when characters are too 'perfect'. For example, Ayla from Jean Auel's books. She was great in the first two, then she became too annoyingly 'perfect'.
