Impressive shading here. There are a lot of curves and contortions in the glass which distort the shadows, but you brought them all out very well. Very realistic. Artistic, too, with the composition and the placement fo the orange, being the only colored spot on the picture, which is also well rendered. It's not perfectly curved in some places, but otherwise it's fantastic. Very nice work.
wow I really love his. All the picture is b/w except from the orange slice, which, btw, is excellently drawn. well done
