Still Life Drawing

Here is my new digital art. I drew from life objects.
This still life drawing is a composition of three objects comprising of a gallon, a can, a small grinder and a small rubber a bit separated from others.

The work was started with outline sketch with focus on getting their dimensions and perspectives. This was followed by initial shadings using cross hatching and a few scribbles.

Darker shades were introduced to add forms and base to it. Finally more darker shades was introduced and I shaded the left side of it which gave rise to a negative space.

This piece was done with AutoDesk sketchbook application and aided with an S-pen. You can see my steps below:

Thank you.
