I tried to use the red alarm clock as an icon for my open-source alarm clock, but I don’t like it compared to other icons.
So I thought I’ll give you some feedback:
I saved the red alarm clock as an *.ico file and placed it on my desktop next to the skype icon, since it also uses 2 colors and a gradient.
What I noticed was the absence of white areas, rendering the icon to a red dot on my desktop. (Yes, I’m dramatizing here)
What I would change is to make the clock face white to give the icon a recognizable shape (a red dot with a white dot in the middle). You could use a gradient on the white surface, too.

I hope you see my post as a constructive critique.
