When you want to describe a person, animal, thing or place with more adjectives, you should take care of the word order:
General qualities (our opinion) go before particular qualities (size, age, shape, colour, origin, etc.).
Also, tend not to use more than three adjectives before a noun.
One more thing, although there is a general rule, a lot depends on your wish to make something sound stronger.
