modify face expression (not sure how it works in details but as a result it should be a pic of a professional looking guy, the same as it's now)
maybe rotate the face a little bit
change the background (make it something like dark gray and remove white square)
the picture will be provided (original picture 300px * 300px, 90dpi, note it will be a profile picture so I will resize it to 72px *72px later on)
Since I don't know how the result should look like, I want to do it in 3 iterations, when I give you my feedback and you change the pic according to my feedback.
