This is a very solid still life study 👍
Drawing without grids really shows your observation skills, and it’s paying off here.
The forms feel stable and the cylinders are handled well. Your shading is clean and controlled, especially on the taller objects. The light direction is clear, which helps everything read as three dimensional.
For improvement, you could push the cast shadows a little more. Darker shadows at the base of the objects will anchor them better to the surface. Also, try adding slightly sharper edges where one form overlaps another. That contrast between soft and sharp edges will add realism.
Overall, this is strong work and shows good discipline. Keep practicing like this 😊

Thank you Ali. I appreciate your comments. They are really helpful. As always your instructions are excellent, and very easy to follow.
