Tiny Timmy and the Army of Snails - CDC "Mouse Warrior"

My entry for this month's Character Design Challenge. I just couldn't miss this theme, though I wasn't sure I could finish it before the deadline as I had waaaay too much work and no free time. A sleepless night did the trick, though :D

Here's a quick backstory I wrote for this cute little guy:

"Tiny Timmy was the smallest mouse of the Village, lightweight as a feather, not even bigger than a harvest mouse. Being so delicate, with such a frail body, he was not allowed to join the army when the Ferrets attacked.
Tiny Timmy was, however, incredibly smart. Being the runt of the litter, too small to play-fight with his siblings, he had spent a lot of time dreaming, befriending other inhabitants of the forest and learning everything he could, so he would one day be as strong as his brothers and sisters...
Then came the day he had been waiting for during his whole life. What better way to defeat the Ferrets than to trap them into a gigantic pool of slime?"
