Ph.d Student recommendation or Reference letter, template

I.U.H made me referee for his Ph.d admission in a European university, I.U.H is very near to me, he was in real a very promising and obedient student & lately a close friend. The university later sent me an email to write a reference, i was first thinking to use some template, but as i never like ready made stuff, at least for writing, in my opinion it kills yours creativity...so i decided to write it by myself... the university had some limitations on size of reference letter, so i had to be very precised, i am publishing this reference letter here, i wish it is helpful by any means in your case ! , i will appreciate if you can add some comment on this tiny writing and advice me to correct it for future...
