Nice icons.
I'm a little concerned with their "flat" nature.. the rest of the world uses 1:1 icon sizes, I don't see why Amiga icons have to stay as if they're going to be stretched vertically, especially these days.
At the very least I'd say icon designers should try and
conform to the lastest UI design guidelines for other
operating systems, seeing as we have no longer have current
ones for AmigaOS or MorphOS..

imagery. Standard drop-shadow sizes, positions and
opacities, and the use of "real text" shrunk down instead
of wavy lines, minimizing the number of elements in the
icon and so on..
From what I can see your icons match those guidelines anyway, apart from the jarring "widescreen format"
