looking for constructive crit.

Particularly from ivylore  or anyone else who has had the good fortune to see an aurora.

Are the colours too 'pretty'?  The theme of the book is that everything (particularly polar bears) are all the same colour, so the aurora is supposed to stand out.

Anyway, I'd like to hear your opinions.  :~)
