Sedge warbler burst

Sedge burst1I started this in the summer and forgot about it it. It is a Sedge Warbler I watched bursting into its song flight from a dry flower stems in the large bed of Rosebay Willowherb at the North of the reserve. I thought of using watercolour to bring about the bright red mouth of the bird onto the painting, but I think it is going to stay as a pencil sketch.
