This model has the basis for promise. I can approve of the fact that it retains much about the original, it gives a good basic starting point at the very least.
As for maps vs mesh, Texturing can be handled many different ways. Some methods will convey detail, others will obscure it.
In the end, it come down to the fact that there are very few people that work on FreeSpace models of any sort (by comparison of TCs or other mods) that virtually any thing can be an improvement, even this model. If tetxtured better than the existing model, while it may not make for the same uberfication as the Hatshepsut, it will at least give us something more optimized and usable that what we currently have.
And at the end of the day, the important question isn't "does it have moar greebles than the last one" but "is it usable and at least aesthetically meaningful enough to warrant its use".
Without knowing anything about it's geometry as I haven't opened it, aside from needing some more refinements in the texturing space, I call the mesh itself a good start and I look forward to seeing how it progresses, with full credits if/when it goes in.
