Geometric Shapes sketches - Volume one

Geometric Shapes sketches - Volume one, This project contains some pages from my sketchbook, in this Sketches, I focused on the contrast of the shapes that were in front of me, and how can I play with the light and the shadow. So in this way, I become able to control how far and near the objects on my paper. Add on that, the background plays a vital role in my sketch. For example, if I want this cylinder to look far I fade it with a shaded background, and that's it. Thank you.
