Coming back to a director met during holidays

Hello,

I am doing an internship in a BB bank (Tier-2) in London until September 2015 (I started in october 2014).
It is a "project management role", nothing to do with IB or so.
I chose it with the hope to make a lateral move to the front office.
I am a non native English speaker so I found it good to have a first working experience in a full english speaking department).
I had a master with a concentration in finance (financial markets & corporate finance)
At the moment, the reviews of my superiors were very positive.

In fact, during my holidays in August, I met "completely out of the blue" a director (from the Amsterdam office, headquarters) of the IB division in Amsterdam. He knows some important people in the London offices.
He asked me what I was doing as a job. I said that I will do an internship, and it replies to me by saying that he work in this bank for 20 years. I asked some questions about the bank, the markets....
Before saying goodbye, he spontaneously gave me his business card and he said to me to send him an e-mail in January and he will "try to do what he could to put me in relationship with people more in front office role".

So, after 4 fours months. I will send him this e-mail. I was thinking about the following structure:
- Seeing how is doing
- Explaining my four first months of internship (pluses, what I learned, why I appreciate this bank).
- Explaining my motivation for investment banking (why,....) like in a cover letter
- Asking if he has other ideas of other departments that he knows and which might be interesting.
+ sending attached my CV

Has anyone been in the same situation as me?
What do you recommend? and what are the mistakes to avoid?
In fact, by this, I hope that he will transfer my CV to people that I know and that it will accelerate the process, having an interview... (simplifying the traditional HR-process: online testings, phone interview, 2/3 interviews).

Thanks for you inputs,
