Quite a bit of that may be involved in seeing only the subject material at hand and not seeing the light. You could take a picture of an empty soup can in great light and make a good looking picture, but the best scenery under bland lighting looks, well...., bland.
Try to involve yourself in seeing the quality of the light and you may start seeing a difference in your shooting.
