If you draw a cube in mathematics class, and then a cube in art class, they would look different, because mathematics requires you to measure the sides and make them all equal, which is not what you see in real life. Real life has perspective.
No, that wasnt condicending, it just sounded sort of silly. I dont know if you read the title or looked at it, or the previous image, but its a logo, not a scientifically accurate drawing. Adding even simple perspective, will help make the simple design, more complicated, which most logos hope to avoid. Next time you want to tell someone to add perspective, you can just say try adding perspective, i really don't know if you looked at the rest of my gallery, but because of what i normally do it is very silly to explain that to me.
thats fine, then just give a crit saying you feel it could use some perspective, but to go out on a limb and explain to me what perspective is and how it differs from a flat, or orthographic drawing, was just hilarious, and makes it harder to take your actual crit seriously.
