Photoshop Work

I've been having trouble with design board work for my Friday portfolio modal. I've tried to smush together some of my sketchbook work with some of my glass. Started messing around with a sketch but the results weren't getting me anywhere and the whole thing was getting me down a bit so I decided to cute it up a bit and this is what I came up with....
Cheered me up a bit :)

Below is the portfolio/PowerPoint page I've been working on. So far I think the images are strong but compared to some of the portfolios I've seen so far I just think its a little dull, and I haven't got any ideas of how to spruce it up. To be honest I think I would rather have a portfolio of images.
