aim: explore the grid perspective tool
First I added a grid by clicking the perspective grid tool, I added shapes to it by selecting what point of the grid I want to add it and draw it onto it. if I made a shape outside of the grid, I would use the perspective selection tool under the perspective grid tool.
I made a present by changing the grid to 3-point perspective, and created a 3d shape.
WWW: I was able to create a 3d shape. the shadow worked well.
EBI: use the gradient more
