I think my preference is for the grave image too. Although all three address the them, I think this is the most interesting and creative interpretation.
If crit is welcomed, then I would suggest you think about experimenting with composition a bit more; all three of these are shot fairly square on and might have benefitted from a different perspective or control of dof.
If crit is not welcomed, tell me to mog off!
All the best for your next 50
