Good simple, modern and honest appearance. Well done for avoiding being gimmicky for the sake of it. One of the pictures on the "Faces" portfolio does not show though. The 7th from the left between the female graduate and the drummer. Looked at on my iMac & MBP, I don't have an iPad to check that appearance for you, but it doesn't work too well on an iPhone, if you wanted to, you could look at a scalable appearance for your layout, so it works across all viewing platforms.
Thanks! I think I fixed it? There shouldn't be a photo in between those two photos. I'm working on making it scalable for mobile.
