Avocet study

This is the start of another small drawing for my forthcoming exhibition at Titchfield Haven.It's a study of a lovely Avocet on the mudscrape at titchfield.So far ive layered the background twice with an H grade pencil and worked some areas up further using HB and B grade pencils.The water was layered only once with H grade and then i blended it using a paper blending stump to make it appear smooth.I completed the avocets head by layering with all grades from H thru to 5B to get the very deep black required here.i'm going to be working on this one from top to bottom because it's so vertical in it's format and because i fancy a change!
