The challenge with Greenland is to draw semi-circles.
The crescent is a popular device. You may be able to draw a circle in the foreground colour, then draw an offset circle in the background colour over the top.
The four pointed star must be filled in red and outlined in white.
The black lines should not be drawn.
Previously we were drawing five pointed stars using 10 points. Those stars were filled. Ethiopia has a star that is not filled, only 5 points need be used.
