The making of do do

This is a drawing of do do, one of my dogs. She currently lives with my mum in HK. She should be 18 years old now in dog years but she is such a lovely dog, how I miss her...
 

I always start off with the dark areas, it seems to help me get an outline of the shape and where everything goes, I then start with the eyes cuz, well i suppose if you get the eyes wrong there isnt much point continuing...lol
