Looks good...lathed the saucer this time right?
I like the looks of it. Unless you like the faceted look of it, try smoothing it. Just go to the modifier panel, choose smooth from the drop down list; chk autosmooth and it should smooth out the right angles.
Keep up the work, you're getting better...hell at least you can design you're own ship. Me, I just do stuff from other peoples designs.
