Well, for Dimensional Eclipse, Droid and I are working a slightly alternative version of the Phobos, so you might be interested in. It matches the texture style of the FedCom ships though and not Esarai's. It's also a lot more streamlined with half the greebles cut off and remodeled. It looks so much better to my eyes.
On a side note, I think you should consider changing the ship names, as there's a fairly consistent, though not 100%, theme to the names of UEF vessels (Karuna, Narayana, Purusha).
