Commute Sketching II: Sketching on the go
Like I mentioned before, I have been using my brush pen to draw on the go very often now. It allows me to fill in the blacks and I usually start drawing the hair (shapes) first before going to the ear and then to the face. Sometime its the gesture that I started first, which is the curve of the back or the front of the body to nail down the pose, sometimes I began with the face if the passenger or the commuter is up close, like drawing a portrait. Ink flow doesn't better, so using a used brush pen might be advantageous because you don't want too much ink to come through to the bristles. Dry brushing is also good to add some tones to your drawings.
Comparing brush pen to iPad's Procreate, I prefer brush pen. Simple reason is, the outcome is always unpredictable, while the brush strokes are a lot more gestural and energetic.
