It looks ok, but are you going for a properly realistic look to it?
The microphone looks pretty good, the materials could do with some work, but the moon looks out of scale also the shelf its sitting on looks flat and lacking in detial, and the window dosne look like its actually there, more like its in fornt of a monitor.
Its also hard to see if its on, theres not much detial on that, it might sound harsh but it seems a bit half done, good model of the microphone but bit lacking in the composition, materials and render.
