Sora's new look.

They posted artwork of Sora for KHIII, I can't post it right now because I'm my phone at the moment. They said that Sora is gonna be older and mature in KHIII, but he looks younger than he did in KHII. In the Kingdom Hearts III artwork he looks 18, which is the age he should be,in Kingdom Hearts II he looks like he's in his early 20's when he should be 15. Anyone else agree?
