The model and texture are fantastic, actually.
Everyone must bear in mind that when HTLing ANY ship, a large portion of what is to be done will come from the artist. There simply are too few decent references to tell what V would have done. Take the Sath... Shape you can copy, but since the textures are largely tile maps, any details must come from your head, as I am positive that V would not have modeled the repeated details in the retail textures if given the chance to.
In the case where textures are not tiled, then they are truly the only reference we have... there is no telling the motives behind the design choices of the textures, be it due to stock/available textures or intentional design. Which ones to keep and which to toss are entirely up to the designer.
The other issue that arises is one that arises anytime anyone tries to redo something from way back when. Take Deus Ex: HR. It is, by itself, a good game. If you pick it up and expect to play the original Deus Ex, you will likely be disappointed. Now apply that to these models: On its own, a fantastic model. Compare it to what you think the Charby should look like, that image that has been in your head for years, and will not match up.
In both the cases of the game and models, members of the community will have a choice: Either except the new, or be constantly let down. That does not mean that you must like every model that comes through the door; instead it means that you need to judge a model based on the craftsmanship. Does it look well made? Does it look Terran? Does it look like a ship that is built for the task it was designed for? This model is a "yes" on all three accounts, so it gets an A in my book.
If you walk in an and ask the question: "Does it look like I think V would have wanted it to look?" you will almost always answer "no", occasionally "kinda", and very seldom ever "yes."
