Shouldn't be any clear lines brother. That breaks it up and hides the "seams" but most importantly gives the floor strength
Looks like railroad ties

Typically 3-4 board length differences
Did you gap the edges of the room on all sides? Typically leave about 1/4" for expansion or the floor can buckle with warmer temps and higher humidity
