Hello Aure!
It looks like you've got a great start for Hinata -- Well rounded kid with a large family and a great personality to go along with it. I do have a few things to note about her civ side of things before moving on to her powered side.
For the blood type, we do need to know whether it's O+ or O- -- a little thing, but if you could please specify which of the two that would be wonderful!
When it comes to Hinata's bravery, what makes it a virtue? The way you have it worded currently makes it seem a bit more like the bravery that would send her into 'scary places' or try 'fighting off monsters' could be more dangerous, which would lend better towards being a flaw. I would recommend either tweaking it to other forms of bravery or consider changing the virtue to independent and possibly noting that despite being from such a large family she's not afraid of doing things/being alone.
I would like to pose the same question when it comes to Hinata's cheerfulness. The energy is great and staying positive is wonderful, but what are some examples of how she uses that cheerfulness to her advantage when it comes to interacting with others?
Her flaws look great and I love her style! It's always lovely to see what characters look like in their civilian styles as opposed to their school uniforms.
For Chibi Sailor Amaterasu -- Design-wise, she checks out, especially with the addition of a sailor-collar on her coat.
As for the attacks that you have laid out for her, I'm afraid that they don't really read as
sunrise, and instead give off much more of a Sun or Holy Light feel with a side of Hope where both 'Sun' and 'Holy' are restricted spheres, as is 'Hope'.
I would recommend taking a look at
Super Sailor Adria, the Senshi of Sunsets. While I am in no way suggesting copying the attacks that Kyu laid out for Sailor Adria, they are a very good example of how the imagery of a sunset (sunrise, in your case) can be used to inspire attacks without using the sun, or anything aligned too closely with it, itself.
There is also a Senshi of Dawn that has been approved previously, and while I am aware that sunrise and dawn are two different things, we'll have to make sure that we aren't stepping on any toes in that aspect as well.
If you have any questions or would like to toss around ideas for attacks, please let me know. Otherwise, I'll be back around the next time you quote me!
