Awesome flash
It was wonderful, especially the lizard; he's very cute. It was really funny to see all those aliens' eyes go with the eyes of the lizard. The music made the movie even more appealing. And I didn't think that the mountains needed more detail, this flash is cute because of its simplicity.
One thing you could explain better though is what the aliens wanted. Did they want to know who lives on planet earth, or just make friends?
Maybe it's just me, but I think that you could've done more with the ending of the story. Maybe a small hug or something?
