most common viewers will notice the use of colur + light shadow in this image and praise it

most viewers will not notice how elements are repeated
prime example of common big medium small shape arrangement

most of the time artists will arrange it so the small shape is slightly more towards the left or right and not equally spaced between the large and medium shape


current example however is more evenly spaced

on the left we see another arrangement, big, medium small

on the right we see another arrangement, medium, small, big

the general method of creating the overall layout is
create objects in groups of 3 with varying arrangements of big medium small shapes
create other elements that overlap it in more natural/random ways to make it not so obvious
when viewed, these 3 shapes are seen as a group

another example - 3 repeated shapes in small, big, medium with variation in the gap between

notice all the different shapes that are repeated, from the long pointy towers, to the ground level pots, to the elevated pots, to the triangle base, to the dangling vines

notice the focal point, this diamond shaped opening that only shows up once in the entire image

the other focal point is this ship, which also only shows up once
