There are 4 more pyramids which are only black outer line. Then you make "sun" in corner with two sevens and then try to put all 1s which are left there as a light coming from there.

I somehow figured it out. Couldn't have done it without Ketu's hints. The placement dots are the tops of the pyramids. The 2 outside pyramids (dots) are closer in the foreground. The sun rays make a sort of checker pattern, except for the lower left sun quadrant where it looks like a couple blocks are omitted.
