Your icons look cool in the pictures, but ugly on my computer. Your icon colour depth is too low. Windows, by default, typically displays icons at 16 colours. Hopefully I will have a simple utility for this problem up soon. For me it's relatively easy, because I was drawing pixel by pixel, in programs like MS Paintbrush, since I was small.
New people have a relatively ok learning curve, if they're graphically inclined.
Then some, especially people who've used things like Adobe Photoshop making huge and complex images, have an absolute fit trying to draw icons. To put it simply, it depends on the person. Microsoft Image Composer. Only reason I bought MS Frontpage 98 was because it was the only way to get this program.
