Wow! That's amazing that you have been able to do all of that so quickly and single handedly too!
The script, the gags, the models, the voices and music, animation and editing ! Wow! Well done!
The lack of eye and brow movement bothered me a little but I gather that was by design in order to cut production time. The voice of the green alien grated after a while but this is subjective. Just my personal, hyper-critical opinions.
I love the intro music. It has a touch of the Hitch hiker's Guide to the Galaxy' about it.
Very impressive!
