I don't normally give advice but there is something I can say that should help. To the point, it looks like there are two different skies. The bottom section is a darker blue that he top part so it looks more like an irregularly shaped mirror. The sky should flow from light on the bottom to dark above (you did this well but you did it twice.
The only other thing that stands out to me is that there could be more shadow under the arch itself. That would give it a more solid look as well as make a better contrast with the lighter sky below.
I hope that this helps! Keep at it!
