Greetings and Peace be upon you.
This is my first participation in a digital art competition.
I'm not very skilled in Digital art as I am in traditional, nor do I have fancy equipment, just my fingers and a phone.
I found the picture on Pinterest but unfortunately, I have lost it, so I'm sorry but I can't put the reference.

APP:

Ibis Paint X.

STEP 1

I use a heavy brush to sketch out the glass first.

STEP 2

I use the reference and add the colors at the needed places

STEP 3

I blend it with white using a airbrush.

STEP 4

I add highlights and other details.

And its done!
A complicated drawing made easy in four steps.
I hope you liked this drawing.
I invite @hamzayousafzai @roominaz and @mrnazrul
