Nicely done! I like the way your haiku starts with a specific image rooted in nature (the rolling plains) and then generalizes the imagery to be about the Ancestors. The blowing wind makes a nice connector between the physical world of the plains and the spiritual world of the Ancestors because the wind has a physical effect but can't be seen. Lots of thought put into a few powerful words.
Hopefully its a $100 Netflix gift card nice.
