We might have figured it out, had you shown us the console output from
your command. There's so much useful information in it, honestly!

Well, what you're doing is padding something originally 640x640, and putting it on
a 670x670 canvas, with an offset of 15, which is exactly in the middle
((670-640)/2 = 15). If you want the top border to be larger, increase
the canvas and the offset, e.g.:
or just put the overlay lower:
It really depends on what you're trying to achieve (exactly).
