That's about as straight forward as can be. The entrance screen isn't too bad, although it "stumps" you at first until it becomes clear that the IMAGE|FILE is actually meant to access the pertaining upload service. I'd add "Upload" over top of these two.
Once inside the site, i would recommend to keep the frontpage design and pull it through. The white box is a bit distracting, i'd rather keep the backdrop all the way through, but build a frame around the content section.
Other than that, solid work! :tu::tu: 2/3
