Terry Gilliam would be proud
That was good execution of a well-used technique but it just seemed to lack something. An item I'm failing to put my finger on.
What you did was technically excellent but the movie, for me anyway, lacked that element Gilliam had back with the Python gang. That total sense of the bizarre. This isn't so much a criticism of you as praise for him. Maybe you just haven't fucked your head up quite enough with the mind-bending power of ze drugs ;)
In any case, you've put together a fine string of images and sound effects and I don't really know what more it was that I was hoping for. Anyway, I do look forward to your further attempts at this sort of animation as I'm sure they'll only build on what's been done here. A good effort!
