On my past few drawings I have taken photos while blocking out then overlaid them in my photo editor to compare to the reference photo. Some of my proportions are quite good, others not so good. I can make a great comparison this way when drawing from photos but it won’t be very practical when I can start drawing from live models again. I also have a proportional compass I use a lot to check measurements.
Is using the photo editor and compass A good practice to learn to see proportions better or am I cheating?
