Hello, I'm Yumi!
You said it was difficult to control the water, but you calmly colored it well!
Overall, on the far right, in the black mixing compartment,
I think you've got a lot of water.
I think it's because I'm afraid it'll get too dark with black.
In that case, if you mix more of the medium ton of paint than water,
It can be expressed in a more vivid color!
Fighting:)
