I'm not sure what their story is but I thought alot about their character and personalities while drawing and coloring this. You can say that I was partly inspired by the character diversity in the Lord of the Rings and alot of RPGs.
Here's what I came up with while coloring this:
-The squirrel is a ranger who likes to think that he's the leader of the party.
-The turtle is a chivalrous knight who doesn't mind carrying the team on his back.
-The frog is an excellent swordsman but is a coward at times.
-The mouse offers her support behind the group as the healer.
-The crow specialzes in casting violent black magic spells under her calm exterior.
-And lastly, the rabbit is a crafty but laidback thief/ninja that likes to have fun at the expense of his fellow comrades. I'm not sure if he's got traitorous blood in him though.
You can come up with any other character details if you want. Enjoy.
