FIND A NEW THEME
Wow, how many nuclear apocalypse films have you made? (answer: alot) And how many of them are just slideshows of 3D models with minimal animation? (answer: all of them)
Fisrt, the use of a blank faced 3D model just turns this film into an emotional vacuum. He mourns the loss of his wife...by staring blankly. He mourns the loss of the world...by staring blankly. He mourns the fact that he can't emote...by staring blankly.
The backround graphics were great, but I'm not sure how much credit i can give you, not knowing whether you modelled them all or not.
Just try to move away from the nukapocolypse theme and expand your animation.
