I just edit it until i like how it looks.
To me, that's not really editing.... it's invoking the Infinite Monkeys Theorem.
In my book, editing an image is the last step in the entire process of creating the image. That process started back when I picked up the camera. Once I identified a potential image, I set the camera to capture as much of the vision I saw as possible. Editing is only necessary to do what the camera was incapable of doing.
So, what did you want to convey with this image? What did you want to tell us about him? From there, what steps are needed in post to further expound on your vision?
Yes, most images can be improved with a bit of an S in the curve, a slight increase in contrast, and some sharpening. But not all. Editing isn't a cookie-cutter process. Edit each image on it's own merits and needs.
