Sugomori's shading tends to be very soft and flat.
The lines tend to be thinner too (I think they use the inking tool on paint tool SAI or maybe manga studio). Palette is quite pale but it still alternates towards colours (like greenish → yellowish, reddish to a very light orange, slight bluish → brown).
Faked the shading with these water colour settings in SAI

Most of the details are lost on the sprite, though, so if you're spriting do the linework, size it down and only pixel over that. Don't shade/colour as it never carries over and the sprite art essentially only uses two colours for each part of the sprite.
