cool but to be honest I don't really know what id use these for
maybe you should use a more creative design
but these are ok...

I don't expect everyone to be able to use all the icons I make. My icons will appeal to some but not to others. Just because you don't use them does not mean that others will not. Everyone has different tastes and requirements in an icon. I believe this design is rather nice because it is so simple, 3d, and the icons look good.
This icon design should be judged on those factors and not on how much you personally like or have a use for the icon design.
