Couple of cool stuff going on your site, little here and little there! Saw what you did to your page title :)

Love the way you use your initial name G as your main design element.

One suggestion. On Projects page, would be great if all the background images are in monotone. So it won't clash with the project numbering and View Project. And also your design element(initial G!) can have a strong brand presence across all pages. As I think this design element is quite the main charm of your site.

Keep it up

I like a lot of things, yet, some other things should be revised in my opinion. Let's start with the "thumbs down" :)

I'm not sure the navigation should be displayed the way it is: 2 links only. That may me think the information architecture could be improved. Speaking of which, I was a bit confused with the project page. Would be cool actually if I didn't have to click a second time on the tiny "view project" link to display the full project (put the link on the project number too).
Are the home and about page really necessary (as they are)? I think they could be merged and each project should be accessible directly through the home page (as there are only 4). Last but not least, sometimes the navigation is almost invisible because of the contents beneath.

Now the thumbs up:
I like the simplicity of the visual aesthetic, I like the way this simplicity and the main colors (blue and red) are introduced via your logo, I like the contrast of the font you use, I like the way your works are presented (variety of devices / full screen screenshots), I like the fact that you show the colors and the fonts used in each project (even if the colors don't need such BIG circles, and I would have appreciated the name of the fonts), and I like the consistency of the design and transition throughout the pages.

Overall, a pretty (very) good job :P
