Thanks! Yeah, the forehead wrinkle idea seems like it would be nice actually, the intention was to add some surprise that a big eye would come out of that small deformation in the forehead, but I can see how it could look weird. As for the outlines, I'll probably never do this again, I was experimenting with anti-aliasing and it ended up just being bad, I might try again later, just not in an animation...

This is a neat idea, but it bothers me how the eye-hole for the third eye has to stretch. I get that it's slime and can do what it wants, but it just looks very weird (and not in the good creepy way). What if the third eye's eyelids were much bigger even when closed? They could look like a shallow forehead wrinkle. That way, it could be an even bigger surprise when it turns out to be an eye.

The outlines fade to a lighter colour outside, is that intentional? Is the stage very light-coloured? On PJ's default dark grey, it looks very jagged.
