First, my apologies if you are unable to see the drawing well as I'm using a H9 pencil ๐
I need to make it light to avoid the pencil markings from bleeding through the oil pastel.
I've always had problems with perception (but then again, who doesn't?) and I can't tell you how many times I've had to erase and redo my line work. Now that I am getting into cityscapes, knowing how to get the right size and angles is crucial to get an accurate street view. Again, I used the grid method to pre render my drawing and I had a "AH HA!' moment when working on the buildings.
For once, I finally saw the city as just shapes.
Rectangles, triangles, trapezoids, etc. Everything is a shape of some kind. Once that clicked, I began to draw just shapes and everything just came together. I wasn't trying to draw a curb; I was drawing a rhombus. Everything just made sense and I was able to trust the process. I could still feel my brain try to fill in what it thought was there but I just focused on one square at a time and created the angles I saw.
This is an exciting victory for me. This is why learning the basics is so important. If you've always had trouble with perspective, definitely give the grid maker a try.
