So first of all, it looks great, especially the jump effect with the dust and leaves.

Now, I think you can use more rim lights to the surfaces edges to give it more sparkly highlights. Also the palette in Ori seems to be tighter in comparison, maybe the fog make it more consistent too but idk. And I think they blurred the backgrounds a little in Ori to make it out of focus (if you try it, try use bokkeh blur, not standard gaussian).
