Cartoon bats

Here are some bat character designs that I am quite fond of, I think they all work well for kids and are not too scary. Some are more detailed than others. As this is being designed for an animation of some length, I think it would be a good idea to make my design not too complicated. I like how on some of these the wings are being used as hands. I intend to do this too. I can't decide whether to go as far as to actually give him hands though like one of these designs or if thats taking it too far.
