Swim as easy in the sky

' . . . as in the sea, because there is water up there too,'

Yet another one of my silly alternative, added to titles, hahah! I guess this is slowly becoming a thing.

This started out as brush practice, but quickly spiraled out of control. Overall, it probably took about ten hours total over two days. Time that I should have spent on Algebra. 

What I'm looking for in critique: any advice that I receive will be taken into consideration for the next work, instead of going back and fixing this one. (unless it's something simple like the placement of the fish or bubbles)

 

Special shout-out to , as always, for hand holding.
