First off, great work on Yama River species textures and models!
I am a carp enthusiast like many others. It would be a really incredible addition to the game if there was a possibilty to add the same feature for carp species. As you all know, every carp is different. I believe it would be amazing to have random textures for carps of all species like we have now for Coho, Chum, Chinook and so on. By no means, I am not specifically reffering about the colors.
Keep up with the graphics improvement! I really enjoy the graphics so far.
