Hi erich, i really like what you did here. I’ve done a couple prismacolor renderings (architectural) for school, but i never thought the 3d program could do it as well.
A crit or two: I dont know if you tried rendering without the edge weight or not, but it would be nice to see it without the edge for comparisons sake.
2ndly, the direction of the stroke grain should vary between different planes (grass /sky, wall/grass, wall/roof) and there should be more gradiency in the textures, depending on whether there is shadow (dark areas) and light (edges of walls, roof). I do not know how you would do this with a tiled texture, but maybe there is a gradient texture in Blender.
Otherwise, i really like the effect, i guess you made these textures in PS and then textured your 3d model? Nice job btw.
