The first one is a bit overexposed, I would have liked to see more detail in that large headstone.
The second one is more interesting to me. I like the wavy shadow going down the tree. I think this shot could have been improved a bit if the trunk was positioned a bit more to the right, so it isn't right smack in the center. Generally following the rule of thirds will give you more interesting shots.
Welcome to the forum! Let us know a bit more about your equipment (what kind of DSLR?) and settings (what mode were you shooting in? and what aperture/shutter speed did you use?) and we may be able to help you out a bit more.
