Please help to identify spaceship-like LEGO set
Between the blue pin and the grey plane nose bottom pieces there is a characteristic white wedge piece, which I have searched for. This piece exists in three different designs, each of which is only contained in sets that don't resemble anything like the build your image depicts:

https://brickset.com/sets/containing-part-4614247
https://brickset.com/sets/containing-part-6249584

On another path, I searched for the 2x2 brick with two balls, under the golden plate at the back, with the same results:

https://brickset.com/sets/containing-design-57908

So this leads me to think that your build is not part of any official sets, or it could be a somewhat modified part of a set.
