sorry for the crappy sky but i don’t have a better hdr map… anyway tell me what you think…
Here’s my honest opinion. It’s very cute! I like it.
Now if you were going for realistic, then no. It’s not realistic.
But if you were going for cartoony, like something you would find in a Super Mario game, then 400 thumbs up! It is very cartoony, and cute 
Ditto to what Robo said, it looks very nice. But if I were you, I would decrease the reflectivity of the water somewhat, and scaled down the displacement texture. Right now I find the water too ‘coarse’ if you will.
Good luck!
tnx for the feedback, i’ll continue tomorrow… i was indeed not aiming for realistic, so thank you!
