Good concept, opening montage created a good setup which worked well in the juxtaposition of then walking down the road. It was a shame that the flow you started didnt continue. Its was good that you didnt let the story wonder on for too much longer.
Not so good, middle part was bloated and was not as interesting when the other character did very little. Ending was O.K and I didnt expect it, but having said that, it would have been very very very unlikely to ever occur. Suspension of disbelief?
Technically, you kept to one side of the line well and when you did cross the line it was done mostly correct. Watch your background (with the crew in it). And just a tad bit of colour correction/balancing would have gone down a treat.
Be good to see what you can produce next year.
