sky, give it some complementary color maybe? Like very low-saturation orange
lines on the ground. I know you’re just using wireframe mode, but if the lines were same thickness as the lines on the path - it would blend in better
shadow. Maybe a shadow would help ground the character into the scene better. Perhaps an old-school circular contact shadow if a projected shadow break the style too much.
Oh, whilst creation, I tried all the options you listed here
And maybe because of my mood, phase of the Moon and the weather on Mars, I came up with the decision to keep amount of colors at minimum, pavement lines of the road has to be not the same as lines on the terrain, and I don’t want any shadows from the model (even that old school circular one). I liked that imperfect and minimalistic style of the scene
Just a small addition to what has been said above.
In one of my posts, I mentioned that - as in this example - I was having a problem with textures becoming blurry out only a short distance out when viewed at low elevations. When scrolling through the latest three.js examples, I realized that I could partly solve that issue by setting the material anistropy property. That option may not be available for all graphics cards and may slow things down a bit. I expect that you are well-versed in the mysteries of anistropy. So I am merely adding this tidbit of information for the benefit of others who, like myself, are just learning about these kinds of things.
