B&W 刷畫靜脈在生物體上,如人類或動物。 B&W brush for drawing veins on an organism like humans or animals.
至於使用這支刷子,我建議從四肢開始向心髒拉。
如果你有比我更好的手/筆控制,你可以讓容器看起來比我更自然一些。
As for using this brush, I advise to start drawing from the extremities towards the heart.
If you have better hand/pen control than I do, you can make the vessels look a bit more natural and than I did.
