Does this kinda work?

Hey,

Just did this the other day and would like to hear ways to do it better. I know the main photo could have been more interesting, I just wanted to experiment introducing objects in the sky.

I like it!

Its not workimg for me. The object in the sky looks translucent and the lighting doesn't match the rest of the scene. The key to compositing is matching the light, both direction and color/hardness.

It is supposed to kind of imitate an immense object in orbit. That is the reason why I chose to make it translucent. I agree with the remark about light on it. It can be done better

you have the translucent part on the wrong side. the lit part should appear solid, and the side away from the sun would take on more of the translucent (same color as atmosphere) look.

i also think the death star should be rotated clockwise to match the angle of the sun. The monument isn't straight either.
