"snow effect" for logging scene and water movement for river scene

I learnt how to create snow effect through this tutorial on youtube and by changing the direction and color of the snow i was able to create this effect of the wood and dust flying around the frame as the loggers are cutting down the trees. This made that shot vibrant and interesting adding that extra layer on the animation.

I made this river move reflecting some of the weird clouds of the sky, i learnt the technique from this video on how to reflect and place displacement map on the layer. However, i than twitch it to only the river unlike the tutorial that made the entire bottom half of the frame to water.
The reflection is not actually the image of the sky to create is "weird" water reflection effect.
This signifies the radiation in this area of chernobyl unlike the scenes before this.

Both of this effect adds to the overall aesthetic and mood of the animation, however i feel that both of the effects are rather partial and sticks to the narrative. Therefore acts as a part of the narrative rather than a stylistic effect created for aesthetic purposes.
