Excellent char! However, there are two small details in the sheet that must be changed before I can accept her :( But it shouldn't take too much tedious revision I hope!
If she has no occupation, or has no home, or does not deal with money (not just valuable wares) or her earning it, this automatically makes her position "pauper", since positions address social status rather than style of life. Also, it sounds like she could have at least two occupations: hunter and freelance soldier, since she appears to have joined some military cause in the last line of her History? Or perhaps that jut described her mental response, in which case she'd be a "hunter". Does that make sense? Was there a different occupation you had in mind?
So while I actually don't find this contradicting, and I think it is well thought-out, I feel like it does leave her personality a bit ambivalent. Perhaps the introduction of when certain responses are triggered (offense to her pride, offense to the forest) or what situations make her feel a certain way (injustice, gratuitous violence) could clarify the gray areas and help other players find Yudee easier to understand, and more predictable.
I like your analogy to the rose with thorns! Still, it doesn't seem like Yudee is typically "sensitive and fragile" to other people. Perhaps she feels these emotions when someone is in pain, or only towards nature. While you do continue to say that she hides these feelings because of her beliefs, which is a great and valuable thing to add, other feelings she has include ruthlessness, coldness and cruelty. If that is all fellow players think they will see in her, it may be hard to make a char that interacts constructively with others in the plotline.
Yudee does not seek out battles, but if someone wants a fight she won't refuse. She is a capable fighter and will not spare lives in a necessary battle. Like I said before, I wouldn't address them because I think they're contradictory – I don't think that. I just believe, as mentioned previously, the statements could use some refinement. Clearly she has a lot of pride – in herself? her race? her nationality? her god? the nature she protects? her way of life? her magic? Also, why doesn't she seek out battles if this is true of her? Does she deplore unnecessary violence? Does she dislike fighting those who have done her no wrong? Could she be pushed into a deadly battle if someone repeatedly taunted her without directly challenging her to a duel? In battle, she spares no lives – this indicates fierce loyalty to her side, and a cold indifference to the other side. This is not inconsistent with the rest of your CS, but it might be useful to mention that outside of battle, she won't go around slaughtering anyone who isn't Argenian. Unless of course this is true of her, in which case your char would be a radical nationalist and evil, since she endangers the other PCs.
Hope that helps! Let me know if you don't think my responses are appropriate – I'm here to make the game more safe and enjoyable for everyone, not make people feel crummy about rejecting their ideas!! I'm looking forward to your other character! :D
