Brush pen quick sketch whilst waiting

Waiting outside the surgery, Pentel Brush Pen, A4 quick sketch Waiting for my mother to have her blood test done - a regular trip - I sketched the view from the car again.  Music on and a sketchpad and I don't mind the wait :>) This one was done with a Pentel Brush Pen - unforgiving but lovely to use.  I decided to use the brush pen as I knew it would be fast - last visit I only got this far and she back out and ready for home ........ sketch done in biro A4 From a different parking space, obviously. It isn't easy to keep lines straight when leaning on the steering wheel is it?
