An awe-inspiring masterpiece... The overall form is well-structured (which must be exceedingly difficult on such scales) while the details are elegant (the largeness of all parts also make them look way more realistic from a distance, than what can be achieved on smaller scales). So many nice ideas, all beautifully executed: the enormous railgun jaw, the rotating reactor thing, the engine-like piece in-between, the slanted arrangement of reverse thrusters, the diagonal ring supports, the red-glowing hangars, the giant engines... And bless you for deciding to include a warp ring on a titan :D Congrats for finishing a work of sci-fi art on this level!
