Tiling in Blender is of importance. But also in game worlds.
I did a test run to create Isometric tiles using Blender 3D.
I thought it would be great. But I have no experience on that matter.
I created a basic wall with the brickwork shader. Just to see.
I made also grass as a basic floor texture, using particles.
This orginal one is 640x640 and I like the texture and details.
I’m liking this last render the best, as now it doesn’t look like such a uniform duplication of a small patch of grass. It’s definitely looking more random, which is how real grass grows.
I like the way your pawn came out, and the two different sizes in this last render is a fun render. I agree with you that shadows under their feet would add that little extra something needed.
