Not a wise choice of picture to enter in this challenge. The building appears naturally white and clearly comands to be the main subject of this picture. The red plane cowling might appear interesting to other flyers, but, it's too small of a plane fragment to be a good picture of a plane. With the fragment highlighted and the main subject subdued - it's a confusing photograph.
There's a bit of gray on the plane at the top. Either you missed it or intended to keep it like that. But it does give the impression of a bad job. It's an interesting shot otherwise.
I love your perspective here. So many people would focus primarily on the plane. The "195" lets you know what it is, and the tower is effective. I can't wait to see more.
