Expressive?

I went to theater and watched Pokemon 10th movie recently. That's a good movie Except for the plot(too short), I was attracted by some of its composition and music. It's really moving when the tower plays the last Oracion melody. I got some inspirations from this movie and wanted to draw something. However......how to make a static drawing as touching(expressive) as the movie without music and animation? I tried last time but failed -_-||(mbrsl.deviantart.com/art/Light…)
Does anyone have any experiences or suggestions about how to make your work more expressive?

前幾天到電影院看了神奇寶貝的第十部電影，整體而言算是不錯的作品
除了劇情太短外運鏡和音樂都很棒，最後時空之塔演奏奧拉席翁(Oracion)很感動
看完之後手癢想構圖，不過...到底要怎麼樣才能畫出一張能扣人心弦的作品？？就像看到電影最後那一段的感動......但一張靜態的作品不像電影有動畫還有音樂加持
之前就有試著挑戰....不過上次嘗試表現出電影中亞斯的情感實在不是很成功-_-||(mbrsl.deviantart.com/art/Light…)
有人有想過這個問題嗎？要怎麼為一張作品注入不可思議的說服力？

如果看得懂中文的話請回中文，我的英文表達很糟XD
