Well I've been teaching myself little tricks. Some are more suttle than others.
Like the Picture below of Michelle and Sai, it actually was really dark and had a blue tint to the whole thing. You would never know it unless I told you.

In this one I did alot. I made the backround b&w and also blurred it. I intensified the colours and added some sparkle to her eyes. A little phrase on top to explain the expression on her face.
