Well this is what I have to say this is amazing you sure do have a talent when it comes to drawing,I thought it was a photography.As for the shading it is stunning and the light as well.
Pencil has always been my favourite means of expressing myself on paper. I used to make sketches years ago, though... LOL This is so very interesting, dear friend. Thanks. SAM & SAAB
Wow!!! I can't believe this is a drawing. What got my curiosity to look at it - who would have such a grey & empty room - that you took a picture of. Beautiful talent.
