Hello everyone, I am here to show you my first digital dark light lesson, I am learning more and more about all these color combinations, it is funny the process because I had no idea what I was doing. Anyway, I hope you like it and learn some tricks.

And with this brush I began to make the dark light.

Then I started to design a nice background for my beautiful sphere....

- The reflection is ready!!! ...it looks like a rubber ball ? I made a shiny reflection at the end.
I wanted to see how it would look creating a dark background.
- In the end I didn't like it and I kept the white background I had initiall
My first attempt at dark light is dedicated to 
At the end after touching up a few details I added my signature and that's it.
