I really need to achieve exactly this, but with like a perfect white with super clean black lines.
Image 1 & 2 are from enscape with mega tweeking even though.
Image 3 & 4 are some post-p I did on photoshop to try to just get the black and whites.
Thing is my client wants no shadows. She wants to draw the rest herself. So when there is grey areas it messes the colors.
