Let's play Spot the Difference.

I'm certain I made this shape in #Shapez2 correctly, but the validator still says it's wrong. What am I missing?

Edit: Probably not the black outlines; I don't know how I'd add those.
Also I've looked this up and all the hints I've seen for this level are for the shape after this one in the sequence, so *somebody* must be getting it right.

Edit 2: we got it! @Canageek noticed the bottom purple shouldn't be two-tone (should be a circle segment, not a crystal).
