Wow! This is great, Christel. I love the look of charcoal. This black and white kitty is the perfect subject for it.
Happy to see you posting your work! Yes, it might take a bit to look around this place and figure out where to post. For example, both soft and oil pastels are posted under the Pastels forum. A little different.
Very nice shapes, body position and expression of the cat.
However I don't know if the black contour is adequate for the white fur. It seems somehow strange to me. Would it be better to define the shape by just putting a darker background in that part of the image ?
