A picture of a typewriter i made a while ago and have been working on a bit in spare time today.
Render simple. Not realistic. The composition is bad. I would focus the camera on a typewriter, and the ship would put somewhere back on the shelf, for example.
I recommend to read about the preparation of the composition. This is an important element in the picture.
And most importantly - do not stop! You will succeed!
Hi Sandra! I saw this on artstation. 
I think Pavel is right, start with a better composition and everything will gain a lot.
I would also work a bit on the shaders. Try to use some map to give variation to the roughness.
Thanks for the suggestions.
