The Zolly app is fantastic! I need to work on the perspective of basic shapes and this app is perfect for that. I have been drawing cubes using the app. Also, I made use of the 3D model airplane. Two very useful tools! I have attached 3 sheets of practice. On the page with the model plane, I utilized one of the early lessons by roughing out the plane at the bottom left corner.

Hey there Mr. Marshall Vandruff, came across you on YouTube via "Proko" YT Channel Videos and have been learning a lot from you lately. How can I get the FREE ZOLLY APP to further enhance my drawing capabilities and intellectually? Thank you
