Interview, havent heard back

So I managed to land an interview at my dream hospital for my dream job. The interview went well, I thought. The interviewing manger kept saying things like "the orientation you'll get...." And "your preceptors are...." And the like. After a few "you will get/we will set you up with" he would quickly say "if we offer you the position I mean"...so I thought it went well. That was last Friday (not this one just past, the one before). I asked how long it should be before I hear back and he said a week to a week and a half. I sent a thank you email about an hour after the interview, so I did that. I don't want to bother the guy, but today is a week and a half and I haven't heard anything. I'm thinking of sending the following email. What do you all think?

Hello Mr X,

I just wanted to say thank you once again for the opportunity to interview with you last week. I wanted to let you know the interview was very informative and makes me want to work at XXXX that much more. I was wondering if there were any pointers you could give me for the next interview down the line, ways to improve my interview skills? As stated in my interview my "dream job" is at XXX in the XX department. If you have a moment perhaps you could give me some pointers for the next time we have an interview once I have more experience, I am eager to impress you, so I too can find my "perfect job" with XXXXX.

Thank you again,

ItsNowOrNever

My husband says it sounds too defeatist. What do you think?
