G'day and welcome to the SARP
I can see a couple of problems with your bio, so I'll point them out as I see them to help you out.
First thing is that you can't have a 24 year old Nekovalkyrja. I can't find the post right now but I believe that the oldest Neko in the SARP is 22, and if you are going for a Ketsurui Samurai then you can only choose from an NH-22 or 27, which would put your maximum age at around about the 4 year mark. (Don't quote me on that, can't find a date in the CCG)
Which brings up another point, you haven't specified which model of Neko your character is. Information on the various types can be found in the Character Creation Guide, on the Sexes > Other page. And again, with the Samurai occuption your choice within those is restricted.
The physical description is outside the 'norm' for a Ketsurui Samurai; it may be accepted to have her as a blonde, but it doesn't and won't fit in with the expected long black hair nearly all other Samurai have.
I also thought that being a Ketsurui Samurai required you to have been around a while, but I can't see any mention of that in the CCG and I have seen fresh players take them up before so it may not be a problem.
The history is nice and short, which a number of people would be happy with as it leaves you to RP out everything, but 24 years of solid training is a hell of a lot and the Ketsurui Samurai occupation page on the CCG says that they only have 1 year of initial training.
Apart from those main points there are a couple of small things you can do just to make things a bit more presentable; using bold text for headers, and not going to the 20th decimal place on the metric units for example
Hmm, hope I haven't managed to scare you with all that writing. Either way, don't go rushing out to change everything now, I'd suggest waiting to see what some of the regular bio-checkers have to say first.
Hope you get eerything sorted soon and have heaps of fun here
