Are my top teeth too big or do I have an overbite and can it be fixed without braces? (Photo)

Hi I've recently taken off my braces and my top teeth look too big but I don't know if it is due to them being too forward or if that is just their size. Is there a way of making teeth smaller? Also I think I have a cross bits. And my gum line is not even/ teeth are slanted. Can all these be fixed without braces.
