Sure. Broadly speaking, first, the goals in my personal statement were too broad (read: fluffy) and not specific enough, relative to other applicants. There is strength in specificity. Second, my application package as a whole lacked a specific gap / gaps I wanted to fill via their program -- which makes sense, right -- if I were perfect I wouldn't need to apply to school. So the implication was that my package could've been strengthened if I were more honest / aware about my weaknesses and more intentional about how the program would address these weaknesses.
