Hey, you wrote it! :D And it's very IC, both in tone and attitude as well as how he may view those characters. I think it expands on those relationships while remaining true to what's been presented canonically (and it's probably more thought than what Kishimoto's placed XD).

Anyway, this is not even a question, but in the name of all that is holy, why did you have to be so stupid?

I love that! XD It's funny, but also has a tint of pain and bitterness.

(P.S. Only minor, but I think there's a typo in responsibility under Sasuke)

P.P.S. I never noticed it in the original picture, but Sakura looks kinda like Tsunade in your icon!
