as the full moon is my muse, you illustrate it is big and bright as it has ever been in the milky way tonight.

I would take out "full soft" since in the pic the moon is obviously full, and 'soft' doesn't add anything. Remember, haiku don't have to be 5-7-5. This is a lovely haiga. I love that moon pic! smouldering orange is the perfect way of describing it.
