To be honest, I don't like this one very much. It's better than anything I could do at the moment, sure, but I still don't like it much. I think the background is kind of cool but I completely dislike the whole light overlay design-thing (for lack of a better word). I just think the picture as a whole is too gray and bland. Add in some more color or just make the background more vibrant or something... I don't know.
Still, technical-skills wise, nice job.
