I have seen a student turn up at a architecture mid term crit with a few piece of paper pin to a board, a mess. We all thought, he's about to get torn apart for not doing his work. TBH, its lazy, it's no work on display, or very little, its merely some sketches. Compared to some of the others who clearly put lods of hours and days into it. Then said student stands in front and did his presentation, and he is a smooth talker, and he knows how to try to draw the attention away from the crap drawings in front of the teacher and try and concentrate on his idea only. And the tutors were lapping it up, i could not believe my eyes.
He simply talked himself out of a fail into like a C, by pure BS technique.
A piece of work should speak to you without the author standing next to it and ram those explanations into your ears.
But hey, that's art right.
