The colors are just a bit too bland. Olette's eyes should be green I believe. Try brightening her shirt and Roxas' hair up and darken Olette's hair too.
I think she did it to avoid over-saturation of the manga scan, but yeah I agree. I love Hayner's expression in the background. Great transition of the orange-like color in the window to a close to white color. You're really good at this. :3
I actually really like the colors in here. A little tip I'd like to give: When you're doing a manga coloring, it always comes out so much better when you re-do the lineart and put a lot of work into lights and shadows. I usually color manga on a larger scale though, as in one panel, not a whole page. It may seem like a lot of work but it gets to be a quick process. These quick colorings are good for manga though, although I have a tutorial that can help you get a light/shadow in here without much effort if you'd like it. That's pretty much crit for all your colorings. :3 Also I love Olette too.
