Well it was a bit long

Ok tips for improvement.

The walking shots with the character in shot work much better than when we have movement and he is not in the frame. I dont know if the game engine allows you total free movement of the camera but if so I would try and keep the character in view from various angles whilst he walks.

The panning shots are the weakest as when they appear it has that horrible first person viewpoint that I dont think works.

Its good that your trying to tell a story, i.e. the journey home to the grave. I have never played Fallout 3 but the landscapes appear very similar and very unphotogenic. I realise its meant to be set in a post apocalyptic world but geeze it looks drab.

I didnt like the music to be honest and its crying out for a nice mix of music and sound effects. Have you ever thought of trying to act the voice of your character? and dubbing that into the movie. Could be fun to do.

Most people around here won't comment on such videos but I can see they could be fun to make and it does force you to think of and reproduce interesting camera angles.
