Honestly, this is pretty good. It's better than what I could do. I like the subtle touch of Roxas/Ven's wristband. It might be messy on the page as a whole, but at least the sketch itself is clean.
This is good, I do like his jumper xD I do think now (I know it's only a sketch so they wouldn't be there anyway xD) is add some clothes creeses as his chest looks a bit flat and feet a bit too small. Apart from that it looks good, I hope to see you add to it ^^ (like a crowd of KH fans :3)
It looks great! I do like the bracelet he has -it don't looks like Roxas's?- and the heart is perfect. I wish I could draw like this. X_X Well, anyway, it is really great. =]
