I'm supposed to be writing an essay right now so sounds like a good time for me to do literally anything else!!!!
Looks-
I'd like to start out with you're probably the first person I've critiqued who's done a more detailed description of the character's appearance???? Though you are missing the weight, we still got a bit of reasons as to why he's got a bodily build like that, and a quick answer to the scar in the appearance! The Looks are often difficult to critique because I can't say "hmm don't like his eye color" or anything, but as far as I'm concerned you did a pretty decent job describing his appearance. Another thing I'm thinking is if you could explain the Irkallan race. What does the average Irkallan look like? What are their capabilities? What are they known for? And other details like this could give insight to his character.
Nature-
I totally relate to the mannerisms; though it made me realize how little I thought about tiny things my characters do when interacting with others or even when they are alone. As an aspiring animator, it helps me to know that my character might twitch his nose when he tells a lie or walks a certain way when he's in a specific mood, so I understand the need to describe mannerisms. Under motivations, you don't necessarily have to do this, but it might help to give a quick word to explain who Irkalla, Ruka, and Vetriel are and why he has those goals for them. Under flaws, I really like this! I mean, as much as one can like character flaws, I'm glad you're able to go in depth and give him more than a few harmless flaws! I like the mention of his worldview, that is definitely a vital part of creating a character, so it would help to have his entire worldview developed. As far as I'm concerned, I don't think his personality conflicts with his flaws either, so good job with that! I notice the hobbies and talents are missing, so I'm curious what they might be for him.
Social-
Back to explaining the Irkallans, same goes for the Irkallan faith. Is it a religious faith? Is it monotheistic? Polytheistic? Something else? I myself am creating a religion or two for my characters, but I have a tendency to pull from the ideas of Greek/Roman religion, as the people in my story have tendencies similar to ancient greek times. Under the favorites, kudos for giving some background to his favorites! It unlocks a few little facts about your character you might not have realized at first and it really does give more background.
History-
Hey this is too good for me I'm 100% interested I'm too blown away by it to properly critique it but I will try my best uhhh first of all i would die for Tsubaki okay So who sent Ruka? The story implies he wasn't entirely aware of what he was doing so I'm curious as to why he did it in the first place. Second why does Ralmalia have this magic? My understanding is that the angels gave it to him? What provoked that? That's all I can come up with but dude I love this???? big thank
