I cannot add a shadow to the rings. They extend to the edges of the canvas. If I add shadows, then they will be off-canvas on the vertical and horizontal edges. The shadows would only exist in the "corners" of the rings.

But I am happy with 4.5.

I am not a fan of shadows. I create my icons many times for my own use. I am a big user of docks. Often, docks will automatically create a shadow or reflection of the icon for me. There may be times when I do not want a shadow. It is easier to find a tool to create a shadow automatically than it is to find a tool to remove a shadow.

I am righting random things for the one reason of seeing if the amount you coment gets you more buttons so... blah, blah, blah giant water melons, and plain nutty bars on milky toast.

nope. but I do like these icons.
