Networking - Coming back to a director met on 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).
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.

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,
