Great skin.
Here's my suggestion...
The arrows next to nickname & personal message are very bold/loud and kinda ruin the nice feel to the skin.
If they was removed, it'd look a look better imo:
But obviously we need them there for functionality, so something a bit more unobtrusive I think would look better.
The other thing is that it'd be nice if the nickname, etc. were faded out while 'appearing offline'. I didn't notice I was offline earlier, because I didn't particularly look at the colour around my display pic.
But great work.
