Just something post-prod as a spectator:
Well, from the begining to where the metro start, there are some shots alternating different lights that, according to me, did not worked that well,
-second 35 is suddenly too bright.
-different light temp from the street and the inside is too much visible in that sense that I could notice it, and I should not.
then, lots of colors stimulations to the green that are useless.
-minute 01:13 is too dark, if he is first in the stairs and in the dark, and suddenly the stairs are iluminated like the Eiffel tower but it is the same
From there to the end it is perfect.
For example, the cut 01:14 - 01:16 is simply perfect!
A little more care in these details and you are soon in Cannes.
