I love this dock icon set! There are a few things though. My computer won't use the yellow away icon. Instead, it will use the blue unavailable icon. However, it did use the yellow for a session, then it went back to the blue after I restarted Addium. What I would change? Make the away message icon red and turn the unavailable icon into a an "idle" icon and make it yellow. Also, the green available icon with the "hi" text looks out of place. I'm not sure what you would change it to though. Maybe an ellipsis or something like that. Anyway, love the set! Keep it up! :)
