Escaped from the hustle and bustle of Christmas shoppers to the calm interior of this church - St Jean de Montmartre. The building was completed in 1904 and is made of concrete.

I used a sumi brush pen and a UniPin 0.5mm. The combination of the two is quite interesting. the brush pen on its own is much to heavy for a detailed subject like this.
