He kind of looks .... friendly? Somehow! Hahaha, like a regular underwater guy who's really just a buddy if you give him a chance to be a friend :)

Sea-bud, for sure !!!

I really like the texture of his skin and fins :D And the colours and lighting are very nice, also :)

I'm not sure about monetizing, but you should look into Makersplace.com and maybe Displate.com ... if you havent ! :D
