Customizing my bow

I met a guy who was using a same bow as mine.  His bow was heavier, but the look was exactly the same since we were using bows from the same company. 
I wanted to customize my bow, so it's distinctive.  I decided to paint it black, and write words that I really like.
I used a leather paint that I bought on Amazon, masking tape on the edge, so I could still see the sheep skin.  I used a Gundam marker pen to write words "궁아일체 일발필중", "弓我一體 一發必中" which means, "when body and the bow become one, one shot hit target 100%"
