The people you found in the thread praising it do that all day, from topic to topic in the add-ons section. They run around and praise everything from the most ridiculously awful stuffty edits to the more decent entries. They usually praise things before downloading them.
The first add-on you make is usually not all that fantastic (I know, my first add-on was the ion cannon). Sometimes it's a great idea, but your first add-on will likely lack allot of features and details that would make it great. This one you made, for instance, could have been a hell of allot cooler if the people using the Daedric player type would get a visual set of daedric armor, blocko style and flatshaded. THAT would have been something unusually awesome. And who knows, maybe later you'll figure out a way of doing just that, but right now this is your first simple edit and you're still learning the basics.
