I have been exploring adding washes to paper and adding remnants of craft papers to my paper before drawing. I think it is interesting to have the patterns underneath the drawings.
Here is a series of drawings I made on a train journey:
I explored coloured pencil crayons and the way colour can bring life to an image. 
The drawings above and below are of people I know, but don’t see very often, drawn from memory. I found that colour made these drawings more interesting, even though they lacked detail.
The drawing below is also from memory, because I saw these birds out the window for a moment, and then they were gone. I drew the lines, and then later added green felt tip to the negative spaces.
