uh its not really dirty, its a filter I have done it in photoshop sometime ago, and it looked better that way, ill try to look if I find the original file.
I think it needs some work before it reaches the level of quality that we've seen in new Elements cards over the past few months.
It's very dark and kind of looks like a smudge in a camera lens. It also uses Photoshop Lens Flare effect which is what all new Photoshop users do, and it's almost always a bad idea.
