You got the shading/sun effect right

Most don't ever pay attention to that kinda stuff. You can always make what you want the viewers to see, stand out, by Blurring behind it; Or 'things' behind the main focus.
Someone said they (city/plane) blend; that's because they are both proportionally in focus. Blur the background just a little, and you can see a big difference.
Overall nicely done
