You're portfolio preview images are awesome. Your crazy, 5 second long, overlay transitions on hover are not.
I'm trying to see your portfolio, please don't make me find the perfect spot on your site for my mouse to sit just to keep from triggering those transition.
If you must have the transitions, make the time to transition out almost immediate.
I'd rather not call any one particular site out, so I won't. Just trying to give some general feedback.
Keep being cool everyone.
