Your choice is excellent. All the four users you have nominated are users who have been working hard for this platform for a long time. They are also good role models for others. @ashkan is a perfect fit for the best teacher awards. And @suboohi and @dove11. Both of them are worthy of receiving awards.

I think @jyoti-thelight fits the all-rounder category. Because I have known her for a long time. She is generally good at many things like art, cooking, walking, photography, leadership. So I think she is suitable for that.
