As always flawless, however
As always a flawless flash, awesome graphics great, sound
However, my personal opinion is that this could be drawn out into an actual detailed story, not base elements of story with heavy detailed graphics.
I'm not sure, but it just seems you are making these flashes purely to show off your ability to make awesome graphics. You do make awesome graphics, but you've already proved this through your other flash animations. The only story you kind of adopt is always slightly mediocre arty representations so I'm left there thinking "I'm guessing the black cloud represents....well it's an alien world it's hard to relate it to much". It's a shame really that you make such awesome flash, but add no dialogue or story apart from basic representations. You've obviously gone as far to think up Bitey, the YuYu ect. but you don't really devolp any kind of story.
But whatever, I doubt you'll get to read this anyways lol
