Water falls animation with white mist Free low-poly 3D model

*** Update: I already uploaded a zip file with animation scene with water falls, mist, grassland made with Blender. Any issue while setting up animation, please let me know. Please see attached image to find where to download the video with real water falls scene, here I made animation in Blender only.

Model was made mostly by loft loop tool, sculpt mode in Blender not by modifying default object, no other plugins. Youtube logo and text were fixed with logo body. Images textures were made by GIMP. Make sure model looks realistic and light enough for outdoor scene, good quality when render in a distance close to surface. Render engine: Eevee.

Only quad in model, no vertices with more than 5 edges, no mark seam during UV editing, overlapping UV, other standards also meet CGtrader requirement. However, I got problem with UV stretch. Please see preview image, I also attached screenshoot for verification from Kodama. Total vertices: 1518. Dimension: 250 x 204 x 20.4 m ( Detail in preview images).

2K textures: Diffuse, Roughness, Normal, Metalness. Two type of material were baked in textures map so it is very convenient to use.

Avaiable formats: glb, obj, fbx ( no embed textures). FBX file , image textures are in zip file

Any question about working process, any idea to improve model quality, please let me know
