is my 200m time good?

This was my FIRST year in track and I m 13 years old so my times might not be too good. For 200m my best was 27.4sec and for 100m my best is 12.9sec. I personally think I have all the speed necessary to get better but I need to perfect my form for both 100 and 200. I qualified for the meet of champions for both 100 and 200 and I was the anchor for the relay team. So what do you think about my times? How should I improve?
