Krystal and Fox (Star Fox)

I was requested I draw Fox McCloud and Krystal, from the Star Fox series, hanging out in a float tank. I do not know much about the Star Fox canon and the only game I remember playing was the N64 game, a long time ago. It was requested that the two of them be in a float tank, but my dumbass did not really know what that meant. So I google imaged "float tank" and what I got were some jacuzzi like tubs. There was this one tank that had a sea shell design that I liked, so I used it for reference. The tub they are in could have been done better, and I think it hurts the overall image. Also, I was halfway into the image before I realized I accidently left out some minor details of what the requester wanted. I tried fixing as much as I could, but was too far into the drawing to do anything major. The water is also shit, in my opinion. Anyway, please enjoy.
