Haa~ You're good! \o/
Nanaki looks his age for a change --he's supposed to be 20something in human years, ne? The Game logo and the concept are pretty catchy as well!
The spear seems kinda out of place with Nanaki, but I don't object to it. It's connected to his tribal roots, and he would have to fight somehow, as an anthro
Personally, I think he'd be more of a savage hand-to-hand combatant, but that's just my vision.
You get my thumbs up on an overal great composition ^.^
