What do you think of my poem?

It is actually quite good - if a bit short. It's strength lies in your feeling connected to those who passed before you - even tho you didn't know them. I can easily picture you there in the graveyard. Impressive piece for one so young...and keep the word "erected." It has an entirely different feel than the alternative being offered. It implies meticulous effort on the part of those who placed the tombstones...
