First off, very well done! Its unmistakably Halloween Town Sora and looks great.
Next, the critique! I think the shoes could have a more pronounced, distinct curve. In fact, in the game it looks as though they have a flat portion of the sole that gives the curl some more structure. Also, its hard to tell with how your arms are placed in the photos but I can't make out if the jacket has the distinct flare from the waistband. If this is something you wanted, using more interfacing inside the jacket to stiffen it might help, as well as finding some way to keep the waist nipped in and more static. I would consider snaps or magnets to keep it drawn close to the body until the flare, but I also am not a skilled seamstress. Also, there is a telltale contour to your chest that might be smoothed and concealed better with a strong(er) binder. Though its very slight and only visible from some angles. If you are already using a quality binder (I like double design) perhaps it will come down to knowing the angles at will mask this shape best and trying to get photos taken at that angle.
