Grey Cloud around Firely Created Video

[Michael Broom]

Hello,

I created a Firefly video from a still of a dragon that I own. After a few tries I got what I wanted, but the dragon moving through the background has grey cloud around it that shows even if remove background in Premiere Pro. 

Any ideas how to remove it?

Thanks aheada of time!
