So I placed a lot of pipes, bridges, containers and so on inside that main structure. Another thing that I included here was the construction site on the left of the image. I wanted this thing to look like it was still constructed.
Now it was time to detail the background (Fig.06). You can see that I put two more buildings in the background to create more depth and reinforce the scale.
To make the place come alive, I also added a lot of lights, smoke, walking people and small details that suggest action and motion (Fig.07).
You can see those details that I added more clearly in Fig.08. Some of the details might seem tiny, but I still like to draw them. Things like smoke, flares and falling particles; to paint these kind of details it is good to observe life around you. There is so much going on around us and what we only need to do is observe and reflect those things in our paintings.
After I'd finished painting the details I added a radial blur (Zoom) to the whole picture. This helped to bring a cinematic effect to the image. I also added a little bit of graining, again to simulate that cinematic feel.
And here's the finished image (Fig.09)!

So there are three important steps that I would advise you to try to follow when you're creating an image:
Try to set up a cool composition and mood. This can come from a very brief sketch, but if it looks interesting as a thumbnail then it will probably be cool when you detail it.
Set up you perspective and make things look proper. If you are working on character design, take your time to set up proper anatomy.
Bring in lots of tiny details that will make your art to stand out.
Of course, these are not rules. These are just suggestions and procedures that can make your art better.
If you have any questions, feel free to ask me via email. Thank you and good luck!
