Your image slider looks great and I have a suggestion to make:
The navigational dots and arrows are always a problem as one never knows what background the images will have!
May I suggest that whatever colour you use - give it a contrasting border.
This way - if the dot or the arrow "disappears" because of the image colour behind then the contrasting colour should still show! Maybe if you have blue dots..... have a yellow "border"? Black dots, white border etc..... Better still.... let us choose our main and border colours!
