You'll have to excuse my lack of photo shop since I'm at work, but I have another suitable program to edit your photo with simply called: Paint.
First of all, I didn't appreciate you posting a half naked photo without labeling the thread not safe for work. Nudity is not tolerated at work, so photos like this can get me in trouble and if I want to look at naked pictures at work, I have to do it on my phone. So to rectify that outstanding issue, I gave the fellow some more clothes. Once that was done, I decided that your photo was suffering from lack of clouds and added some. I used the spray paint tool to capture a more realistic look of nice white fluffy clouds. After that, I noticed a lack of birds soaring majestically through the heavans so I used the curved line tool to add a flock. They're ravens. Majestic awesome ravens. From there I thought it was silly for this man to be doing what is apparently some ill fated attempt at fishing in a location that obviously didn't have any fish present. He doesn't even have a pole! So with the help of the curved line and straight line tool I added a blue hued transparent fish leaping from the waters to show that this chap was not putting in an unecessary effort for fishing where there are not fish.
I believe my edit of your photo makes it pop and makes it a much better and much more interesting photo than the plain, dull, lifeless original. If you would like to learn how to successfully edit a photo such as this in my unique art style, just let me know and we can set up an online tutoring session. Your photos will end up looking just as amazing as mine!
