That's very good.
Though I think you should've put the Japanese characters instead of the Romaji..It would look more..official I guess you could say..Since it is Japanese afterall..But you can leave it like that if you want..
The color scheme is a little bland, but sometimes that's better.
I don't really like the main font. It's kind of... amateur?
I do like the whitespace you have going there, it's nice.
Maybe don't align the text like that...
Overall, I like it. ;D
Thanks for the comments ^^
I'll work on my skills more
