Very nice, I quite like the animation style, the style combined with the fact that your character is called "Goop" just made me think of my old series "Gorp". I really like it quite a lot, I think the areas that could use some start with it's length. I'd like to see something a little longer with a bit more content. What's happens after they meet, why is it significant, that kind of thing. I want to be more immersed in your world. One thing that could help there is the addition of some kind of back ground. If white background is a stylistic choice, you could keep it white and animate some subtle distortions for the simple purpose of creating movement to make the scene more interesting.
Another point, have you considered voice acting? While I like the way you created the subtitles to fit the theme, some voice acting might also pull this together as a project.
Anyway, I love the character design, and the animation style is intriguing. Good work :)
