Combination of different patterns

I used a ruler and a pen to draw straight overlapping lines that together appear as 3 dimensional shapes. This the most sophisticated geometric drawing I've done so far. There is an individual pattern that's been copied 4x4 square. These lined up side by side create overlapping circles and diamonds. The resulting inner circle of each of the 12 individual square patterns is then filled in with other geometric shapes. All of the lines are straight.
