To me. There could be some major architectural re-constructions.
1. Make it only one file input, but an option if press add it will add one more which can be done multiple times.
2. The header could use some help, as adulu said, too normal.
3. You have a easy to remember domain name, if you want people to remember it, put it on the footer and header!
4. lost password should be only next to login fields
5.Should have some clean login fields on the index page, but not too flashy.
6. Categorize your navigation more easier to read.
I think these are great bits of advice!
