This is really good! So ill go through the couple little things youll need to change.
1, in village of birth, yoy will have to update to use one of our new ninja world landmarks, as we have an alternate time to when ninja villages are made, there is no konoha yet.
Simple remove the village of birth part!
2, with specialties, you are able to pick 3 specialties that you can find in the thread here:
https://animebase.me/threads/bio-rules-quick-access.718945/post-21814300
This meams yiu can pick 2 primary and a secondary, or a primary, secondary and apex.
Primary specialties are things like only one handseal for an element, extra tracking speed etc.
You can find more information in the thread as well!
3, even though you have sage mode, because Hinata is a 'canon' character, (which means she was in the series, a character that isnt made up) she can only use what she was seen using in the series. This means you cannot have sage mode on her.
Other than that you couldpodt the bio and have it checked!
Ill answer your other queations now.
1. The link to the specialties can be found in this thread along with its rules:

2.
if I have to learn that means it's nothing to put yet in the bio and you have to train me?
No, so even if you have skills you havent been trained in yet, you can still put them on your bio, but youd have to make a note that youre still in training for them.
Eg, if you boughr med, you could put it on your bio straight away, but it would say in training untill you completed it.
4.
for this I need more kumi?
So scientific tools can either be taken from the scientific tool thread in the jutsu section (bare in mind you rank restriction still)
Or custom made tools in the custom tool submission thread in the custom jutsu section.
Custom tools can be anything you make from watches or laptops to bigger and better things! Ofcpurse they still follow rules, but we can get to that next when i talk about the customs section.
Lastly, artifacts are special items you can use in the ninja world. Some are weapons, some are armour, some are consumables lile pills or medicine. Each differsnt nd unique.
Do these answer your questions?
