This is a short lesson from my course Drawing Everyday Objects that takes you through breaking down a spray bottle into simple shapes.
I recommend taking Lesson 2 and Lesson 3 of the free Learn To Draw course here on Youtube first: https://www.youtube.com/playlist?list=PL-i_GDP6hCKlHXwGiguwu5z3xtYPhjrQK
Then using this members only lesson for extra practice!
