The quality isn't all that bad since the spaceship is decently drawn and this flash actually has a very nice set of colours in it. There's also a bit of humour that some may find amusing or even just a little bit funny. Not a bad flash in terms of effort, clearly it could have used a lot more but it is a little amusing.
The timing of the video is terrible, it's only a few seconds long and there is absolutely no sound to amuse the viewer at all. Not even some muffle music or spaceship sound effects, which is very basic audio to insert even in a simple little flash like this. There's almost no plot, an the one there is is so boring and tasteless there is almost no point to it at all. There could have been voices, or even just a random laugh track would have made me get a little bit more enjoyment out of it. While I mildly enjoyed the sheep and spaceships artwork, features like the background hill or sky really could have used a lot more work than the poor sketch it had. A lot more creativity needs to be added.
Not the worst flash, even a little amusing for such an old flash. But a lot more creativity, sound, storyline work, animation and length needs to be added to make it even worth watching for the 4 seconds it took to finish it.
