I was asked to comment on this, so here goes. The photogrpahy itself is pretty good. There are some great colors captured by your camera. The focus is fatastic as is the exposure. And for being age 14, heck, you have a lot going for you. But what has killed this picture as indicated by the C-score, is the "Interest" factor. It just isn't interesting. You obviously have some expertise with the camera. What you need to improve on is finding more interesting subjects than this. Look for images that will make beautiful desktops. You don't say where you live but every location has some pretty scenery somewhere. Of course, being age 14, you can't drive and get around but maybe Mom and Dad or a friend would be willing to take you somewhere. Bottom line, I can see much potential here. Keep at it.
