This Art is very exceptional. This is a Great Skill you have got here.
For a minute, I thought the Inverted Art was a picture taken with a camera before discovering it was a Drawing made with a Pencil.

I love the way you gave a detailed workflow of how you sketched this.

Lastly, giving the readers a full proof of this Work with your source of Inspiration makes me appreciate your ORIGINALITY more. Artists like you deserve more exposure on this platform.
