Pretty good
As usual, there are pros and cons. Here they are:
Pros:
- Interesting idea to do it in 'Shades of Grey'
- Good artwork and animation
- Interesting plot
Cons:
- Bad choice of music (especially the techno tune, doesn't fit the story at all)
- No voices (I read your comment and have to agree that it's difficult to find good ones, but in general, I'd say anything is better than "text only")
- Inconsistent art. Your main character appears to be 3D rendered and then traced somehow. You hide it well, but in some scenes it's quite obvious. The other characters seem like they have been made in Flash, which isn't a bad thing, but the quality of animation isn't conistent.
- Some of the camera angels you use don't work very well because your don't have a backdrop for your action.
Seems like a lot of cons, but I still think your movies is good and worth watching.
