    Slide 5Acceptable The right-hand column is text-heavy and repeats much of the title and chart; shorter supporting copy would make the comparison quicker to absorb.Both bars are the same colour, so the 41% non-completer bar is not emphasised.

    Slide 8Needs work The chart's long category labels collide beneath the bars, making the two options difficult to distinguish. Shorten the labels or wrap them into narrower, separate blocks.The two x-axis category labels collide: 'Onboarding programme (annual' runs into 'Price cut to £29 (annual revenue'.

    Slide 9Acceptable The caveat panel is dense with paragraph-length bullets, requiring substantial reading on a closing decision slide.The green accent bar runs well below the end of the bullets, leaving empty space.
