New Opening picture (Patreon)

I haven't drawn a picture for a long time. 

I have been writing a program recently. 

So I change my mood to draw a opening picture.

Then I have to go back to the program and I'll post Progress report a few days later.     

很久沒畫圖了，最近都在寫程式，想轉換個心情就先來畫封面圖了。

接下來又要回去做程式，過幾天後會有進度報告。
