Very good
Great style!
The backgrounds were excellent and the smooth animations were good too.
You use of colors and gradients in Flash is impressive.
Only thing that didnt look so good was the main characters walk animation... it was jerky and didnt really express anything interesting about the character... except that it made him look awkward, so if thats what you were going for than thats okay.... but he seemed to me that he should have had a more lanky, expressive walk.
And the other thing is the bee hive thing swallowing up the one character didnt really make sense.
