Sulphur Crested Cockatoo sketch with pencils (I believe they were my old prismacolour pencils). Done back in 2010. This WAS sketched off a reference image, however, I no longer have the photograph and I'm afraid I don't know who the photograph belonged to. If anyone knows, please let me know so I can credit the original photographer. :)

Yes... I spelled sulphur wrong on the sketch >.>
