Hi im relatively new to blender so sorry if i ask noob questions. My question is there is a way to make this spaceship more detailed? Plz add material ideas and a way to make the scene more interesting.

search for details with normals on youtube. you can use normalmaps to show details without creating them. you can also use technical pictures as normalmaps. change them to black and white or use gimp with normalmapaddon.

Go use reference. Google spaceship 3d models to find inspirations. That is how my colleuges find inspirations and ideas to incorporate in the game.
