Can someone critique my story on Wattpad?

I recently wrote a story on Wattpad and would like to improve my writing skills. I want to know especially if I did the characters well. Can someone critique my story?

If you are wondering what the story is about z it's about a unicorn cat and his friends who are trying to stop a sabertoothed cat with ice powers from bringing eternal winter.
