Backed. Backed hard.

You actually take away from the natural sound of your voice as it would come across live (or in a really well mixed and mastered recording) by keeping the reverb off totally.

I’d even say that you could add in the reverb that onnovocks suggested, or even a little bit more and then throw in just the slightest pre-delay, and you’ll get your open mic recording to sound as close as you’re going to get (without a fully engineered mix) to an actual open mic performance in person.

Your voice deserves that.
