What really sells the 2D look and makes this artwork pop is the lineart setup of the flower. Here's how I did it. π
When I applied a simple outline to the flower it didn't look quite right. It looked too noisy.

I wanted to recreate the look from this artwork, where the outer outline looks stronger than the inner lineart. π

So I added 2 lineart modifiers to the same object to have different line weights.
I added a thicker outline on the outside using the Silhouette edge type.

And a thinner outline on the inside using the Silhouette edge type but inverted. βοΈ

And when I combined them it looked like this.π Different line weights add so much depth to the artwork.

So remember to vary your line thickness to make your artwork more interesting.
