Bland Sketching Style

I have been busy in the past few days catering to WT's brief return during the Thanksgiving break. A mother's work is really never done. My painting inevitably becomes the unintended "casualty". But I was able to catch a breather today, and here are the results. Two of the paintings are termed as the "bland drawing" (bai miao) style comprising black line strokes without any colored space filling. Don't they look crisp?
