Yes, I understand it now, I didn't see it from that point, but you're right the square was innecessary, all tho the PO liked it... Thanks for the tip I'll consider it for my next contribution. @nilfanif

On another point, I didn't know the variation of the color were necessary so I only uploaded the monochromatic since it was the chosen color, but I'll do it in the next ones too, and I'll try to make the conversation more profesional too. detail its very important I appreciate your guidance.
