@AdamK - The minimalist look of the icons is definitely the right way to go. I'd stick with the raw design of the icons (in terms of the basic shapes used), though I'd significantly thin them out and make them much less blocky and angular. The colour scheme is horrific and needs to be thrown out completely... purple, blue, multiple shades of green (all of which are unpleasant)... really?!?! In general, UI should be muted, unimportant items should fade into the background and colour should be used sparingly to draw the eye to the element that is most important.
