Spots before the Eyes

I have been busy drawing out my new cat, which has been very time consuming, so I decided to do another dog study with Derwent drawing pencils. This time I chose a Dalmatian from my reference photographs.
It is approximately 9 x 7 inches on a bluey/grey Mi-Tientes pastel paper. I airbrushed a little acrylic to finish him off.
Please note this went through a horrible stage in the middle, but hopefully it ended up OK.
In these studies I am trying to give them a more 'immediate' look, concentrating on expression and structure rather than my more usual 'every hair drawn' finish. It is teaching me to only include what is important to the finished work, so I'm hoping this carries through into my more detailed work, time will tell.
