Creating a villain

>for this blog i decided to excersize my editing skills by selecting a randon picture of someones face and editing it to appear as though they were a villain from a thriller

i purposefully increased the shadows on the persons face to create chairoscuro, this connotes that the person is in conflict between ligt and dark and possibly has a flip personality making them volitile and unpredictable. i increase the highlights and decreased the brithness to make his complectiona apear sick and unwell; as well as adding a dark tint to the corners of the image to make him apear more isolated.
