Character image and color shades

[Tamanegi]

I'm having doubts about if I should include a third shade of color to my two-shade character:

Left and right are how he is currently looking, middle is how I tried to include a third shade per color. I am mostly lost where I should put the highlights on a material that doesn't shine, like fabric or skin, and you can see that especially with his shirt I was mostly guessing.
I don't want the other images to look crappy just because I tried something that doesn't work, but I can see that it adds extra depth to my image. So, any thoughts?

I'd loose the third shade, it kind of clashes with the "simple" style of the character design and, from a practical stand point, you'll make your life so much easier if there's less shades to keep track off while animating.

Also, I'd make the shoes (and that part of the trousers above them) smaller.

I'd loose the third shade

Except for the hair.

I'd mirror Monsieur OUXX's advice, simply because the sort of fabric your character is wearing isn't very reflective, but hair is.

That makes sense, thank you. Progress is slow, but I get to working on the sprites every now and then

I think the extra shading works on the shoes as well. But it depends on what kind of shoes it is, if it's synthetic leather (which most sneakers are partly made of) then the extra shading makes sense, if it's cloth, not so much.
