this is probably not going to be seen (and you probably dont need it anymore) but maybe a dancing something? kind of like this one. these are pretty simple to do and they look so cool when your done. idk if your still using the trackpad or not, but i use it and this was pretty easy to do on it. another thing is just making eyes move. just simple cartoony eyes. you can make them scared, happy, crying, anything. then you can draw whatever you want around it. hope this helps a bit if your feeling stuck!
