Hi Laura! Thank you for this class and was a lovely quick exercise :)Here is my final sketch:
I could't resist on adding a bit of color! About the process:Here is the reference photo:
First I made a quick pencil sketch
Then the first marker lines:
Then I erased the pencil lines but it look too simple and thin
So I used a thicker marker and changed some of the lines
Last but not least I added the dots!
