The problem I have with these icons is the same problem I have with any screenshot of MorphOS i've seen; as individual images they look very nice, and clearly a lot of work has gone into them.
As an icon set, though, there is no "theme" to them; its like a totally random set of pictures. For example, the "Glow Icons" look, while not particularily great looking, had a certain consistency to them. The icons I use on OS3.9 are taken from an Atari icon set, and they all have a similar background "glyph" and are of a consistent size.
Keep up the good work, though!
Just my 2p worth :-D
