homesick draft

Well ,this is my sketch for my thesis animation series, named "Homesick." It will be an narrative film without a story line. Anyway, I'll post updates when I develop more.
My question is: should I add color to it(say, very very light watercolor)? please let me know what do you think.Thanks in advanced.

這是我論文系列作之一的草圖，名為“思鄉症“。這支影片會有敘事性，但沒有明顯的故事。我會繼續放新的進度。
我想要問大家的是：你們覺得要上色嗎（像淺淺的水彩）？請告訴我你的意見，謝啦！
