Do these splits imply bad pacing?

This was my first marathon, so was definitely just happy to negative split and feel good the entire time. I’m wondering now looking back if I left a lot in the tank? I had 1:57 for my first half, 1:48 second half, I’m not sure if I should’ve tried to make the splits more even
