I completely agree with you, but my 3D skills are somewhat limited, I think that a texture or something else would make it better, but everytime I try to add a texture the ending result is not so pleasant.
First, I wouldn't say "limited", you're doing amazing stuff here (I would know how to start a simple block) . So you're the expert here and know far much better. Plus, I think that what you did with the water and some places in the sand is very good and do the trick! As mentioned by Abu Lafia, I think a combination of the first border and informations of the second would be really nice.
