The animated glowing signs are fantastic and breathe life into Telos and the shine on textures is pretty nice, but for a mod that states it tries to "preserve the original look of the game" this is far too removed from the original aesthetic. Textures are darkened, with grays turned to unfitting blacks and some areas looking muddled because of swapped textures that don't look as good. Lights are changed and there's a lot more marbled stone than the developers probably intended, but they do look nice and give Telos a unique flair so I don't mind them too much. I would suggest only using the new animated signs, stone, and lights. I have no idea if the way I did it will cause problems, but I just deleted the textures I didn't want from the TGA files (the ones from the Part 2 XnView package, keep the grill/lattice textures too) and installed it normally on top of the Ultimate High Resolution Texture Pack - HD Upscale mod from the KOTOR II nexus, which I highly recommend.
Here are some screenshots from my game, with high-res versions of the original textures mixed with my selection of the good stuff from this mod.
This one has some fancy experimental raytracing shaders for Reshade turned on which look lovely. You can get them for $5 here: (https://www.patreon.com/mcflypg).
