Watercolour challenge : Coca-cola

A practice of watercolour, an old exercise that I randomly found photograph on google, already forgot what is the original look. Mainly focus on the highlight, reflection and shape. Simple shapes and lines are difficult to draw. I am not good in photorealistic drawing, only try the best to draw and let it be( '_')

這是一張舊練習，隨意在google上找到圖片就畫下來，已經忘了原圖在哪了。練習的方向是汽水瓶的高光、反光和瓶的線條。越簡單的線條越是難畫。我不善長畫像真畫，練習自然而然好了。

ググった画像を参考した水彩練習です。ちょっと古い練習で本来の画像もう探しても見つからなかった。瓶のハイライトと反射と形の練習です。カラチは簡単なら簡単ほど難しいと思います。写実は得意ではなくて、レット・イット・ビーしかない (' ';)

watercolour : Pental tube + white gel pen paper : memo card board with no brand
