It took much more time than I expected to draw out the background, combining perspective with the way it's drawn out, which was difficult, but that's to be expected. I tried to copy and study a scene around Tokyo station, although the details were a little rough because of the low resolution/quality, and some parts were blurred out.
Apart from the background, the other exercises are easier for me to grasp, such as shapes, but I could use some more practice to develop my skills and adapt my drawings to them. Overall, things are going pretty well. I only need to work on perspective/background, so I will keep working on it along with other fundamentals until I get it right.
