Not good.
It is not good to call a girl a little tiger, because it will make other people think that the girl has a very hot temper, like a little tiger, and it is easy for people to keep calling her a nickname outside, which will bring trouble to the girl. It's going to cause a lot of trouble, so it's not good.
When naming your child, you must think carefully, it must be very meaningful, and it must sound nice.
