The planet Lokum, the landless world, for the first time in history of mankind is being vastly explored by the great arc of research. It is said that life thrives below the surface of the water that covers the world, despite being landless. What will we find?

Holy shit, this took forever. I was trying to put a lot of effort into this one. I kept saying in my other submissions how I know I could do better, but I was too lazy to. Well, here it is. I'm sure I could do even more, but I'm a little stuck. I want to say it's finished, but is any painting ever one hundred percent finished? Heh. Please comment and tell me what you think. I am really satisfied here, one of the few times I'd ever be satisfied with something I actually draw.
Please critique me (lightly of course). I want to do so much better and I know I can!
