Good, apt description. The use of first person perspective is always great in stories that deal with massive size differences, though I personally always find it difficult to maintain for the duration of a big narrative. 

The premise, while not unique, doesn’t need to be. The intrigue of the set pieces have been put into motion. With two goddess like figures being introduced. Neither malicious, one kind and the other a bit careless. 

Would love to see more happen in this universe. 

Keep going nice!!!!
