I think you should look at this work of yours as an example of how not to make oceans and water and skies?Before criticizing his work, try to learn from it, because there is so much to learn from this work of Noah. And also, its definitely not fantasy water as these are shallow waters like in reefs which tend to be more green and tan, not deep blue. So if his intention was to make a long length of shallows, this is what it would look like.
