Poor Horace ...
Horace didn't make it this time either :(
Overall, it's not bad but I liked ep1 better.
I didn't read your "Author's comments" and at first I didn't know how he got into the hallway. Maybe, mention that before the movie starts - in the movie.
The dog growling was good at first but the images didn't convey a menacing dog. Also, it seemed to walk after Horace but running/chasing might be more appropriate. Looping the dog growling didn't work for me either. I liked in ep1 that a pigeon eye showed up with the pigeon cooing (is that the right word?).
About Tuti TV: graphics are 75% done but my brother has been busy so we couldn't work on the dialogue and voice recording.
