I have been trying to use the techniques I've learned in Marc Taro Holmes' and James Richards' Craftsy classes. Here are some recent examples:
Using a single line drawing with my extra fine Platinum pen, then adding darks with my Kuretake brush pen, finally adding watercolors
Barcelona
Sketching at a recent SF Giants game - it was cold!!
Just using my Pentel brush pen at dinner last night
Sketching my girls after dinner just using watercolors directly
Sketching at the Claremont Resort with just my Pentel brush pen
