What a digital brush should have been 數位畫筆，早該是這樣子

One Brush, Many Marks   -   No more collecting 'stickers' to give your strokes a different look. You don't even need to adjust any puzzling parameter in the app's UI. Just paint as if in real life. It's  a dream come true.

Just like Master Chef Martin Yan said, "one, two, three, four, five - and it's Done!"  

一支筆，不用調複雜參數，不用找不同的貼圖來貼，就可隨便畫出變化無窮的筆觸。手起筆落，就這麼簡單。數位畫筆，本來就該是這樣子。

Now with the right tool, show me some  rhythmic  lines, won't you,  Master Painter?  什麼叫 ‘韻律’，畫畫的您會懂！

And it comes with amazing details. Below is a closeup of the above stroke.  This is hard to achieve with any vector  or bitmap-based graphics tool out there. Simply put, Expresii is revolutionary in digital painting technology!
畫出來的線條還可以放得很大，這是任何現有基於 vector 或 bitmap 的繪畫系統都難以匹敵的！

Isn't the details amazing?  媽，真的可以放得很大啊！
