I will only give feedback about the Level Design since I really don't know very much about photography.
The first thing I though about was that there was no information on what YOU specifically have done on the parts of level design. Right now, I think it looks more like a portfolio for a Level Artist. Put some texts in there about the screenshots, what you did and your ideas behind them.
Also, include a top-down if you made any, either of the level or the paper-planning.
