'Dat Uhlan...I can't describe the awesomeness.
As for the Kent...it looks good so far, but I can't help but wonder--why prioritize the Kent? It already looks great and detailed, as does the Uriel...and, well, the Izra'il, Durga, and Vajradhara(sp?). If anything, the Aiinsari needs a bit of a makeover to match the aesthetic and detail of the rest of the UEF craft. And the Lao Tze--as cool as it looks--suffers from extremely poor gun placement (aside from its double-Cavalier bank)--it's hard as hell to hit anything with four of its six guns, as the gun ports are further apart than an Artemis' width and height (just off the top of my head guess, just to convey the idea).
That said, your work is absolutely amazing, so any of the stuff you do is a great service to FSO.
