No changes to the physical structure, topper or base, just a density upgrade from 2" to 1", so 150px per strand, rather than 75.I might have missed this but did you change the height etc or just reduce the spacing? Was the thinking to increase the clarity of images/ text or something else? Sorry I'm just starting my megatree planning so keen to get it right first time..
Also went wider from 20 strands at 150 degrees, to 30 strands at about 225 degrees.
Added clarity to images and to effects, also it just "filled in" the look rather than being more dot-like
