My first attempt drawing equal sized cubes in 3 point perspective. Supposed to be one cube hovering high in the sky with two cubes way down on the ground. Struggled to keep the distant ground cubes at the correct size, but I'm a complete beginner at scaling objects. I did everything the hard way too, but it's still off. Frustrating. Gonna have to spend a lot more time on studies like this before I'm ready to draw backgrounds in correct perspective. Might try two point next to compare difficulty.
Ok tried two point. Note to self: two point is MUCH MUCH easier than three point. MUCH. I messed up the composition but I'm relieved by how quickly these can be done:
