Nice idea but crappy conversion.
Points of critic:
- size of player compared to environment
- lack of depth (example the train ride, the bars are always behind the player, though they should be in front of him)
- sloppy replay of clips, no fluid transitions
- your player seems to levitate over the ground instead of touching it
some of these things are due to different angles of the cam, perspective, which made it just look unreal
PS this is not to piss you off, it is just to point out what could've been done better, eventhough it means more work
