Still Life Drawing - Digital Art

Here is my new digital art. I drew from life objects.
This still life drawing is not a composition but the placement ofan object on top of another object.

I placed a moderate food flask on a rubber sit and positioned myself from behind thereby creating a diagonal angle.

I started with outline sketches of the object before using a combination of hatching, crossing hatching and scribble to add shades.
After that, I proceeded in using blurring to add more shades while leaving it background blank.

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

Thank you.
