Learning the art of description

I am facing a rather difficult problem; I think I am at the point where my English is indistinguishable from the native fluent English speakers. But I still find my self with limited vocabulary knowledge, I would like to learn how to describe things I see, hear, smell and feel to be able to express my senses in full potential. I would appreciate your advice on this matter how can I learn the art of descriptions and use strong words rather then piling adjectives and adverbs to be creative which is not.

Thanks in advance
