How can I make this better?

First work on description, minimise to allow for flow so that the reader's mind pictures what you want. This can't be achieved by telling the reader every little detail. Cut right back on the adjectives, popping one in only every now and then instead of in front of every noun. Same goes for adverbs. To try and clarify, if a golden sun rises over a luminescent valley you have a problem; either the sun is the cause of the luminescence, in which case the temporal aspect is inaccurate, or something else is causing the luminescence, in which case it needs explaining. Another example is in the next sentence; portentous storm clouds that then dissipate is at best a tad contradictory and at worst oxymoronic. Another answerer pointed out what's wrong with enthusiastically scampered, I agree with him/her. I also agree with the comment about describing through the speech, for instance if someone asks 'why?' that generally implies confusion and dictates a character's tone, so there's no need to explain it.
