Doing urban sketching with only pens -no sound-

Excuse the fluff in the first close up! I try my best to keep everything fluff free, but I'm afraid it's an inevitable consequence of living with pets. ♥
Trying to do an urban scene using only pens and no guidelines!! I quite enjoy it, and maybe I'll keep using this materials on this sketchbook. ♥
Materials:
♥ Zebra DS gel pen in 0.5
♥ Zebra F301 ballpoint pen in 0.7
♥ M&G gel pen in 1.0
♥ Gelly Roll white pens in 0.5 and 0.8 (I think I only use one of them)
♥ Stillman & Birn Nova sketchbook
