Natural Light Photography

So yeah I have this subject called CLS ( Color, Lights and Sound Management)
Our Activity is that we have to take a photograph using our Mobile phones. so yeah I was kinda nervous cause my phone quality sucks. so what I did is I edited my photo in Photoshop CS6, but our Professor told us that we are allowed to edit our Photos in Photoshop. Hope you like it. It's not Black and white. It's just a Shadow Light thing.
