I’m not a web designer, though from a purely users point of view, here are my toughts, not many, but what the heck!
1. I like the colours, the orange and the gray are easy on the eye.
2. I would change the title at the top, the colour is good, but change the font around a bit, add a logo etc. It just looks too much like plain text on an orange background.
Nice site overall though! :)
