10 Drawings; 2 Colours, Repeated Shape

We were asked to make ten vector drawings using only two colours (I chose lime green and bright yellow as these are colours I don’t often use) and one shape (I chose a circle because I like the look of repeated circles versus. repeated squares).

Here are the ten that I created: (The plain yellow circle on the green background is actually the first one I created and they went from there, but they are appearing in a different order).
