Practicing Sound Design

Hey everyone! I made these 3 tiny examples of sound design for an MMO game, and I wanted to ask you for some feedback. It’s mainly about the abilities, but I also did the backgrounds and some objects (just a treasure chest, with some UI). Any comment would be greatly appreciated!
