Was OK need work..
well basically pretty good.. the storytelling need some work most of the scenes jump by way too fast..
Character animation could use some training.. you only give them 4 limbs while technically you need to give them more.. give the limbs some more layers if you understand.. ^^ and the characters needs some more work on the faces.. the aliens werent even moving anything else than their Insect things when they made a noise.. try to add some more.. ;)
but overall looks good the drawings are awesome and the layers you added on the faces are looking great keep em' comin' but try and practice on what i've mentioned... k? :D
