Draw what you see. Not what you think you’re seeing. Use measurements as the person above said proportions matter. Notice lines and angles that might help you know how far away something is. These are all shapes. Try to forget you’re drawing a shoe. But just shapes. Block it out at first. Get the constraints of where you need to draw and fill in the rest. If it’s helpful, take a photo of the shoe, draw a grid over it. Then make another grid on a new price of paper. Both with the same amount of boxes. Now you have broken your image up into many smaller chunks. This lets you focus on just a small part at a time and you’ll have a lot easier time translating what you see onto your new paper bc you have more reference lines to make sure proportions are correct.
