Still Life Drawing - Digital Art

Here is my new digital art.
Today, I tried making a still life drawing and this time, I chose a gas cylinder.
It's a 3kg gas cylinder with a burner on top.

I placed the gas on a ground as I observed closely from behind and sketched them.

As usual, I started with outline sketches of the objects before applying shadings by using crossing hatching and scribbles.
After that, I proceeded in using blurring to add more shades and this helped to add more dept to it.

The sketch was done with AutoDesk sketchbook application and aided with an S-pen. My steps can be seen below:

Thank you.
