So I decided to audition once again hopefully with a better voice and emotion for Corrin, I want to know if the performance is still lacking or if I am showing improvement on Corrin, please let me know.

Overall it is an improvement although I feel it still needs work. To zone this in more specifically , The first line is delivered relatively monotone. It is mainly caused by a speech pattern I can hear in all of your line and not just this one. It's normal for actors to have that speech pattern, but once you break it you can hear a clear improvement in all of your future performances. If you vary the way you say your words, you can make that first line sounds pretty casual and friendly and that's the type of guy Corrin is. He's an all around easy guy to talk to being a prince and all that good stuff. Maybe hesitate a bit on "I was thinking about..." like you were caught off guard. Maybe on, "Do you have any brothers and sisters?" You want to sound chipper than how you said "I was just thinking about my siblings..." because he was reminiscing when he says that and usually when someone reminisces they get a bitter-sweet feelings. It's all about reading what little the lines provide you and interpreting it with your own twist to make it sound natural. The second line was very, very exaggerated which is not the purpose of that line. That line is more of a "Hey, I'm Corrin. I'm strong and you can count on me and my power," rather than, "I am Corrin, and you will die here!" Corrin is not in combat and isn't trying to intimidate anyone. He is trying to convince the audience that you can rely on him with confidence. If you introduced yourself with the tone of I am strong and obey me, you will probably spook whomever you are trying to win the trust of. The last line, was delivered with the wrong emotion. It doesn't sound loving. It doesn't sound like Corrin is nervous. It sounds like Corrin is really, REALLY mad at whoever he is confessing to. Let's take this situation and put yourself in the scenario. A girl has just confessed your love for you and wants an answer. How do you feel? Nervous? Scared? Excited? Maybe all of the above. Relate yourself to the character. Again, always collect the context of the situation. You don't need to know every follicle of a character to play them well, but you have to be able to read and analyze the situation to be able to deliver appropriately. Tl:DR Think of the purpose of every line. Why is this character delivering this. He is trying to persuade, entertain, confide etc.? And then examine the context of whatever situation it is, relate it to yourself and then deliver. A last note, I did not discuss anything about the voice you actually used. I always stress that the acting is 10x more important than the character voice. I feel like you put alot more effort in your voice type and that took away from the acting and decision making. Even if you think your voice doesn't fit the role, who cares? Put priority on the acting. Directors will go for the better actor rather than the guy that sounds good and doesn't act as well.
