If I might, I’d like to give you some pointers to improve your modelling skills.
Don’t just play by shifting the vertices of basic primitives. Don’t start with torus or cylinder, start with a single polygon plane. And don’t just deform shapes to see what happens, know what you want it to look like before you start.
Say you want a shape like your current Omega Mothership. But you drew it first, selected it out of a paper full of shapes and you know this is what you want to model. And then you go to your 3D editor and come up with something like this for instance, which you can have in five minutes:
The point is, the bottom line, you purposely make what you want. Get your ideas on a paper first. Know what you want to create.
