然后给睫毛上色
Color eyelash

然后图层1给眼睛上一个比较浅比较亮的底色
Soft bright color on layer1

然后图层2，放在图层1上面，设置为明暗叠加，且勾选剪贴图层蒙版
Put layer2 above layer1, set明暗(don't know the word in English) and set layer mask

选择水彩笔，把大小和眼睛调的差不多，选择一个比较暗的灰色，然后参数设成这样
Select 水彩笔 brush. Size about the same as the eye. Pick a dark grey and set the brush like this.

先用比较大的笔压把眼睛上半部分实打实的涂黑
Large force to paint the top half.

然后再用比较小的笔压涂抹眼睛中部，达到混色的效果
Small force at the middle to bland color

然后把大小改小，先实打实的用大笔压在中间画个圆，在用小笔压把边缘模糊化
Smaller size and repeat above: large force to draw a circle and small force to bland the edge.

重复上一步绘制下侧的阴影
Same trick on the shade of bottom half.

然后再加一个明暗叠加的图层，用较亮的灰白色涂出眼睛左上方的高亮（叠加后应该是淡红粉色）
Another 明暗 layer and use bright grey to draw the highlight on top left corner. (Should be pink-ish after the effect of 明暗)

再加一个正常图层，用纯白色绘制下部和右侧高亮（画完后是白色的）
Another normal layer on the top and use pure white to draw the other highlights.
