Hey Aure!
Lets see if we can get Tachibana ready for a stamp shall we?
First, I want to tackle her attacks, there's some critical information missing here. We need to know how long each attack lasts; and how large of a distance she can target away from her. Keep in mind that chibi senshi attacks are typically weaker than a normal senshi!
Now then for her virtues and flaws, I need a little more information and elaboration on them. They are almost there, but they need that little extra push to make them Vitures and Flaws.
How does being friendly help Elspeth? The way it reads she kind of could get in trouble with this, so the virtue waffles a little on being a flaw too. If you can flesh out more of the virtue side of this trait to make it stronger; I think you could leave the downfall with it.
Also, how does being Adventurous help Elspeth? Does she learn new things from it, what about doing more mundane things like trying new foods? What sorts of things does she gain from being Adventurous?
Same verses just in reverses with the flaws.
Think about how her believing she's invincible hurts her, you've got a great start here, again it just needs that little extra push.
As far as disrespectful - think about how she is disrespectful? How does this hurt her, what sorts of things could happen because of this? Obviously she's not punished for it by her brother, but does she do this to her friends? Has she hurt their feelings/could she alienate her friends by doing this? Does she miss out on things because she gets put in time out because of her disrespectful nature?
If you have any questions, need help or just want me to take another look; quote me back and I'll be here!
