I find this a great piece of coloring although, there are some fallbacks here and there. You should give more detail to the foxes. Add sometexture because both look too smooth. Also, the rasengan has become the centre of attention, but if the foxes stood out more, it would have more impact to the picture. The shading should blend in more as I see points where they are just there with no blend. Also, there are places that don't need to be shaded. There should also be highlights that would be caused by the rasengan's light which could help make it stand out more.
Overall, it is a great coloring, but you need to work on the detail, shading, and highlights especially. If there are objects releasing light, you need to pay attention and remember to add the highlights so it could make it seem the objet is attentive. The coloring does seem a bit rushed because I can tell by the debris and smoke, you could have done more to it.
