Simple LowPoly Whale Free low-poly 3D model

A simple low-poly whale. I made an armature that, in theory, works pretty well. Hope it can help. I've decided to share it for free cause I love free stuff. If you want to thanks me in some way, just give me some advices on how to improve my 3D modeling skills. I'm Italian so please don't judge my english: I'm good in reading, terrible in writing. Have a nice day :)
