Here’s another Drawing from the Imagination assignment – three-point perspective (+ two-point vertical).
You can tell when something’s in three-point perspective when there are barely any truly vertical lines – all of them slant off to some point in the distance (in this case, out side of the picture to the bottom, right & left). The two-point vertical comes into play if you want to create an object that has a plane parallel to the picture plane (see the box on the shelf – the edges facing us are perfectly horizontal).
I didn’t use as much photo reference for this, and the thumbnails got buried in my photoshop layers so there’s nothing appealing to post from them, but it was a fun assignment once I figured out the point of view and composition that I ultimately wanted.
