Looking a lot better. Its back looks too flat from the way you are shading it. There would be a highlight along where the back bone and haunches are and then it would more quickly turn into the core shadow than the way you have it. Think of the planes that make up the cats body. The back bone is going to be flush with the light while its side isn't. Right now a lot of the side of the cat is fully lit. Do something in between what you previously had and what you have now. That's basically what is shown in the link you provided with the foxes. Think of the meat chunks of the cat like in the link as well.

Also by your current light source, the whole tail should be lit with that highlight part and the front of the face should have less lighting.

I think Decroded means focus more on the anatomical forms and put more light onto those parts like the shoulder blade and the haunches. Also I would expect to see rim lighting on the tops of the feet, especially the farther ones. Although it is not clear whether your light source is straight above the cat, or above and away from the viewer. Think about where that light source is and shade accordingly.

It's not specifically for voxel art but in this same forum is someone converting 3d model renders into pixel art. May be worth a check: https://pixelation.org/index.php?topic=18842.0

Yea that's a huge reason why the mountains still sort of look like cardboard cutouts. I have all the textures flat lit from the front but when the sun is at an angle it can look inaccurate. I'm thinking of implementing something like this using normal maps to my sprites:

Taking a break on the landscape and making the art better for disasters which strike it. I've added forest fires which only occur on fully forested areas and I've added hurricanes that strike on the shorelines. Any critiques on how I can make them look better/more realistic?
