Okay so I have to say you have a really good voice, and you have some nice acting skills as well. The big issue holding this audtion back comes from a sense fo expression. Risa is a very hard character to pin down however something i can say is give it a bit more expression in her tone, perhaps even exagerate a bit if needed. Feel free to reaudtion but if you can balance the energy a bit more you have a really good shot at the role.
Yeah ok! I didn't really know which way to go with her so maybe I'll go through the game again and then reaudition! I wish you luck on the project!
