Do I speak too slowly? I narrate my promotional animated video.

My publisher created a short two minute video to help promote my book. I like it.  They asked me to narrate.  I was nervous about it, because they had a Brit narrate as an example, and he completed the script in 1 min and 45 seconds.  My best in practicing it was 2 min. 15 seconds.  I always knew I spoke more slowly than most, but this was startling to me nonetheless.  I think I got it down to just over 2 minutes.  Give it a look.    The Battle To Do Good animated video.
