How to deal with engine/main gear closups?

[Thomas2]

Hi,

I got a picture rejected due to "part of aircraft cut off":

So my general question is, how to deal with such closeups?
In the database there are several shots of this kind, so what is wrong with my picture?

it shows a bit of everything and simply said too much aircraft for a close up, rather than focusing on a specific motive.
