This may sound odd, but it depends on the audience.

There are the people who know you changed keys, no why, and think it was a good choice. There's really not that many of these in a typical crowd.

There are the people who know you changed keys, no why, and don't like it. This is usually an even smaller part of the crowd.

Then there is BY FAR the vast majority who don't realize you changed the key at all. I'm not kidding when I say it's probably over 90% of the people or more. They simply don't know.

Then there is the other factor. Alcohol. It's the game changer.
