There’s a right way and a rong way to demonstrate expertise.
The wrong way as you can see below is pretentious and lacks social awareness.
In fact I can guarantee you will look like a dickhead.
And you are unlikely to impress potential clients.
The right way:
“Hey I noticed there are several orphans in this typeset. It’s an easy fix. Just do x, y, z. Better yet if you send me the source files I can do it for you. Will take a couple minutes. Happy to help.”
This applies to copywriters, designers, developers, video editors, or really any service provider.
