I remember seeing the female alien and this very cartoon being presented on DeviantArt.com.
I think you did a very wise choice in uploading it here at Newgrounds.com!
Watching this cartoon again gave an interesting "Role-reversal" idea.
Stick with me on this,
What if there was a female robot (Fembot) who is in love with a male human. The human tells the robot that his oxygen tank is very out-dated. So he tells the fembot to race to the Hospital to get an updated air tank. While his space suit puts him into suspended animation for only 10 minutes. The fembot gets back in time to save the mans life. They love each other The end.
One more thing. I can understand why it took you 8 months to make this animation. This animation must be a side hobby for you, While you have real life responsibilities to deal with. ( Going to a job, house chores, caring for pets, dealing with family members.)
If there's going to be a sequel, I can wait for it!
