i really liked your business card but i agree that you should be using more clear fonts for giving your information in front.
I would suggest using a little more lighter colour tone for business rather than the heavy dark tone. The wood-grain print is nifty anyway. Regarding the circle and the kanji character: ◯ <- The circular brush stroke is nice. 禅 (Zen) <- The font is not nice.. My suggestion is to use a brush style font, or something other than a plain sans-serif font. Overall, it is an interesting business card... Keep up the good work.
Looks cool! Fonts easy to read, interesting design, but may be a little more lighter colour tone would be better?! In my opinion...
