Man, your mermaid girl’s looking really good, I can see the small details like the skin pigments and stuff. But our brown friend here seems to be less detailed than mermaid girl! I guess it really depends on how far away brown friend is from the camera. if he’ll be far away then that should suffice very well.
I would suggest putting some bump and specular. I made the mistake of neglecting my specular…
Cheers! Keep up the great work!
