I found this great website on aesthetics. Essentially this author and photographer, Alan Briot has done a series of articles on photography and aesthetics. He believes it is comprised of 9 keys ideas that are important to the aesthetics of your photos, I have listed them below:

1 — How to see photographically2 — How to compose a photograph3 — How to choose the best lens for a specific composition4 — How to find the best light for a specific photograph5 — How to choose the best "film" for a specific image6 — How to determine the best exposure for a specific scene7 — How to decide which photographs are "keepers" and which are not8 — How to assemble a body of work9 — How to establish a personal photographic style

Aesthetics is important in how photos are visually appealing to the eye. What elements surrounding the images being photograhed are important and what adds or distracts from them is also important.
