My two comments are maybe longer shutter speed, and the watermark is really distracting. It looks like a flash was fired?
To add - if you don't completely remove the goudy watermark, I would put it in one of the bottom corners, as a "watermark" (slightly transparent), and maybe not make it so long. Make an "OGP" logo or something so it takes up less photo realestate if you're actually using these for somethign besides showing friends and forumites.
