Okay first...

Hawkeye is a hawk, here he looks more like a chicken.

Moria is supposed to be a gecko.

And Jimbei is a whale shark.

I'm not 100% about Sengoku... but everything else is spot on!

Well Hawkeye may not look like a real badass hawk in here, but surely its not a chicken! And eventhough Moria is called "Gecko" (and "kinda" looks like a giant sized one... maybe), a bat isn't that wrong of a choice. As for Jimbei, it would have been hard to put a whale shark in there I guess :\

Sengoku is Pwngoat. Fitting I should say.

That's one fabulous looking flamingo.

jajaja

the best!!

Gold.
I've found it. Right here.
