Sure, here's why it's not constructive: not once in the parent comment is an alternative suggested or a question raised.

Just a list of things that are "wrong," according to the poster.

It's a resume piece and the parent works for a design company. He's not looking to start a discussion on the merits of the design and how to improve it, only his problems with it from a hiring perspective (polish, consistency, lack of research). It feels very constructive to me.

Then what separates constructive criticism from just criticism?

Parent comment supplied criticism – I'm not arguing that. But s/he did not at all help to reveal a path towards a better outcome. That's what would make it constructive.

Judgements on motive, while critical for investigations and character analysis, are obviously irrelevant to online tech discussions, famously impervious to baggage, ideology, and petty warble.
