The First image is too difficult to see the characters, since the cosplayer wearing the big "R" is so far away and tiny, and the other cosplayer has her hair blocking her face.
The second photo is much better, with the characters being bigger to the camera. The action pose seems to fit the Anime style, but the girl looking at the camera makes it look more like a pose than a real moment. I think it would have worked much better for her eyes to be involved in the action.
This Pokemon posed sitting on the stairs is cute with how the left hand is positioned, and the profile angle of her body shows the person in a flattering way, giving the legs a well-proportioned look. Again, looking into the camera makes it seem like posing for the camera, rather than a natural moment.
This close up is nice with the blurred background to focus our attention on the Pokemon. I like the soft lighting from shooting in the shade and avoiding the direct sunlight I see reflected in the glass behind her. The upward, off-camera gaze seems like a real moment was caught here. I like how she used the wall to motivate a natural pose. The only thing I would watch out for here, is her darker hair showing under the lighter toned wig near her ear.
