There are few words in the english vocabulary which are as vast as nature. When one says nature it can mean; Water, Fire, Earth, Wind. It can mean that which is around us. It can mean the instinct within us etc etc.Giving such a broad name would make me think that the poem would be just as vast.
I have to say i didn't enjoy this as much as your other haiku, but it could be that it seems thoughtless. It seems you tried to copy a style of art in this poem, not actually write a poem.
