Interesting choice! I'm under a similar opinion as xxLelouch, it's pretty rare to see the Fusion colors applied to the original Varia suit but you really made it work, the glowing pieces are really a nice touch.
Absolutely amazing. I usually don't take to the FusionXVaria color variation, but you made it look incredible. I kid you not, this is possibly THE best Samus fanart I've ever seen. Your take on the suit is beautifuly mechanical in detail, making her look acrobatic and technologically deady at the same time.
I'd love to see a version with all the cyan areas purple and the yellow lighted parts blue. Gravity suit is personally my favorite of them all.
But like I said, amazingly well done. I'd favorite it a thousand times if I could.
