Welcome.
I too am going to say it's a picture and not much more. A photograph should show us something or tell a story - a feeling, emotion, something. Unfortunately, this one is flat. I suspect it was something that kind of looked cool to see, but did not translate into a photo.
Don't take the criticism to harshly. I remember a few years ago when I took a picture in picturesque southern Utah. The picture was spectacular, beautiful, awesome in my opinion. Showed it to my professional photographer friend as I was all proud and he said, "Looks like crap." Over the years it has been a running joke that my pictures/photographs still look like crap and the same way he would have shot it. I am also comfortable in looking back at some of my photos and agreeing, they looked like crap.
Keep shooting and keep this photo around. Then one day down the road look back at it to see where you've been and where you are.
Again, welcome.
