Allow me to attempt to shed some light onto this. I read over your character sheet and I can see where the issues lay which seem primarily in the way you've chosen to word certain things. I'll break down your sheet in order to give a clear perspective on why people might not seem willing to accept this character.
Tamare is in short, beautiful
Not really an issue; if your character is supposedly attractive than that's usually completely fine. However in collaborative writing with characters that belong to a multitude of individuals, you'll find concepts such as beauty can be listed as controversial and arguable as everyone has a different idea of the concept of beauty. After all
"Beauty is in the eye of the beholder". So you might find not every character will look upon your character as attractive. I don't believe this to be a major point in your character being a bit...
'much' but I feel it's a good point to remember for future Character Sheets.
Whenever Tamare is training, she's noticed that unlike other people, when she's fighting her mind is clear which allows her to think quickly.
If you look at the way you wrote this, it implies that
"other people" don't have a clear mind and do not think quickly when in combat, which is bound to make people fold their arms and furrow their brows. I for one have a character who is very military driven, holding a high rank withing the Queen's forces, so reading that immediately made me feel as if my character was some what undermined. You could fix that just by changing the wording, or elaborating that she was quicker and more focused than the others
'in her class'. I think it'd make it easier for others to swallow.
Reason being is because she is the most loyal person you could meet.
This is the same issue as above, the wording implies no one else could be as loyal. And again as loyalty is a concept depending on unspoken character it's arguable to say who is more loyal than someone else. No doubt people have varying levels of loyalty, but to define it isn't really possible, unless stated so in other character sheets to which you might than compare to that person. Though I don't advise doing that, just stating she's loyal would have been enough.
Tamare always got the highest marks in every subject no matter what grade
It's fine to have an educated character, I in fact haven't written any academic history for my character and reading this has inspired me to a degree to look into it in the future. However to be the best in every subject and getting the highest grade in each of those subjects is... a little much. Everyone has a subject they don't do well with, for example do not... under any circumstances... ask Azra (my character) a math question. She'll get herself all frustrated trying to work it out on her fingers, however she has a very tight grasp on literacy and literature. But I'm getting off point, maybe toning this down a bit would be a good idea.
Tamare is unpredictable. Especially when she's fighting, cause she'll change her style so her opponent can't predict her next movement.
This would have been absolutely fine, had you not already put this:
Because of this, she can predict where someone's aiming and be able to quickly move or attack.
Being unpredictable and being able to predict the movements of others is way past the line in what is fair by the fighting prowess of characters. Having both those traits makes her basically unbeatable in concept, or at the very least incredibly hard to beat to the point most characters wont stand a chance. I suggest you pick
'one' of these traits and eliminate the other.
Based on what I'm reading of this character, for her to have so much experience and be this level of strength, she needs a higher age. Otherwise with the realistic years involved she'd have been very very young while learning how to fight and the various subjects she apparently did very well in. I think a few years added would be a good idea, or maybe an explanation of how the 'Spirit' race differs in how they age. Example: perhaps spirits age far slower than most other races etc.

I think that's about it that I can see off the bat. To hopefully give some more credibility to my criticisms, I've been RP'ing and writing for around eleven years, not that it makes me any more knowledgeable than the next person, I'm just putting it out there in case anyone want's to contest experience or something. Anyway I hope this helped.
