Hi,
Not sure if it's actually necessary as you as a designer have a square to work within and maybe all of the background is simply left black....
However we like design
#56 as it is now, but would prefer the outside dimensions of the logo to be the same as it is now in terms of width/length....but about half as much in height.
In other words, a similar shape to the Indonesia/UK flags above, i.e. rectangular/oblong shaped.
Thanks.
