Since -most- protagonists in games like this are 17-18 years old, this is my take on what Sora (from Kingdom Hearts) would look like in four years... and a bit more Square-like in design, I think. His shoes aren't the same size as his head now!

Having seen several screenshots from KH2 recently, I think it's creepy I got as close as I did. I think my Sora's outfit is a little brighter, but all the same... this was done about ten months before anything was released about KH2!
