So, since I have a few gem ocs, I decided to draw the corruptions of a few of them. I ended up starting with the first gem character I ever made, Aquamarine.
Here's her normally:

(I made her LONG before cannon aquamarine so she looks a lot different)

And here's the corruption:

I always imagined her to look like a dragon sorta thing with water wings so that's what I ended up doing. I tried making it simplistic so that's why there isn't any complex designs. But I think it turned out pretty good. (Way better than when I first tried to design it)

I didn't even finish it XD. But yeah.
