On the low quality image it is very difficult to see the strings on the balloons as compared to the medium and maximum quality image where they becomes easier to see. Also there is pixilation around the edge of the balloons especially the ones in the foreground of the low quality that gradually decreases as the image quality increases. In the lower quality image the colors aren't as sharp as they are in the higher quality images which is particularly noticeable in the red balloons on the left hand side of the image. the reduction in quality has lead to the file sizes being decreased.
