If it's your first time out with a DSLR maybe I'm right in assuming you're new to the ideas of composition. If that's the case give Josh Cripps' videos on YouTube a go.
He is a landscape photgrapher but a lot of the ideas still apply and he makes videos easy to follow and not remotely boring. https://youtu.be/IpEuYp4_iSg https://youtu.be/9T3zk2LvbYU https://youtu.be/4rsVXfmN_Qo
There are loads more on his channel but I watched them over and over in the beginning and they really helped.
With respect to the photo I think it's a little plain, perhaps coming back a little bit more and making the most of those peeling textures to the right may have helped.
If you're unsure on things in Lightroom - YouTube again is your friend, my man.
