Concept - Nemo (A.k.a "Tyke")

I have quite a few characters that need redesigns, but this one was the one I enjoyed doing the most since I haven't drawn him in ages. This is Nemo. However, among his peers, he's known as Tyke. He is a mouse who is around the age of 12. He's also a bit of a trickster, but he hasn't always been like that. Due to an unforeseen accident, he's found himself living within alley ways and finding ways to get by at such a young age. However, he's got much bigger ambitions, but his current peers advise him not to go through with it. He may be considered a "thug" at such a young age, but deep down he's just a broken soul trying to make it through this cruel world.
