I agree that this is a pretty cool design. I really enjoyed the filter feature of the portfolio.
The black and white hover feature was also cool, but I felt a bit jolted going from the more colorful home section to the grey scale of the rest of the site. But that may just be just a personal preference.
For the about me section, you may want to play around with the font. I found the font difficult to read. You may consider a san-serif font of a lighter weight, and perhaps a slightly larger size. You may also want to consider tweaking the color a little.
All in all, this is one of the more interesting portfolios I’ve seen here.
