It's pretty cool Thebeely, but the demo you released runs terribly slow, and is somewhat unresponsive, and keeps on throwing windows. With that said, I don't think that represents your GUI that well. While it looks nice, and it is rather pleasent to look at, it's represented rather badly, to be honest.
I don't mean to be rude or offend you, I'm only trying to help ya out. It does look rather nice, though, and I do like the style of it. If you need any help with it, let me know, I'll help ya out if I find the time.
EDIT
If you think I'm just talking without any knowledge... I'm not. I've learned some good ways to handle things, and I hope that may encourage you. I'm not trying to advertise this at all, it's kinda dead anyways so I wouldn't be getting any benefit from advertising it.
