the animated gifs: make it transition instead of having it disappear and reappear. at first i thought it was your server being slow at loading images then i realize it's animated. have the first frame show an image instead of starting out blank.

icons: why are they alternating between b/w and color?

featured listing needs its own call-out box. it's featured content, make it look like it.

the how it works section can use some work as well. numbers perhaps?
