Alright LR999, you asked me to check out your clothing variants, and I'm gonna try to pass on a few of my tricks for you :D. I like that you've got so much enthusiasm and energy to make some mods. With a few new tricks, your skins will be stellar.
First up, in the arms and legs where you have replaced the simple tan for some really cool textures: right now they look kinda flat. Usually what I do is to copy the original folds, shadows & highlights onto a new photoshop layer. Then I desaturate it to grey, and change the layer to multiply or overlay. Then I adjust the levels of that shadow layer, so that there is more contrast (move the dark and light sliders towards the center). This will retain the 3D look on those areas.

Some of the textures you've used are really cool. The ones that work the best are the earthy tones and the neutral greys (like the chain mail), because they are analogous to the warm (red-ish) brown leather. The bright colours don't work as well (the greens especially) because they compete with the leather (which is more subdued). One way to fix this is to change the leather from a red-ish colour to a matching colour (like the green).
Second, I almost never use the Hue/Saturation feature to change the colour of something. It tends to make the texture look like plastic, with very little variation in colour. Instead, I like to use the Match Color adjustment. The easiest way is to use it is to have the area you want to change the color of, on its own layer. Then have another photo open in photoshop that you want to change the colour to, and put a selection marquee (marching ants) around the area you want to use. In the first image, select the layer you want to change, open the Match Color, and play with the sliders.

Another way to change colour is to use the Layer Adjustment-> Color Balance because you can change the highlights separately from the shadows.

Third, what I do when I want to make an area look like skin, is either draw the highlights and shadows of the muscles myself, or copy them from one of the underwear textures. You could probably do this for Bastila's stomach and legs, but her arms are a little too blocky (puffy sleaves). I do like how you put the fishnets on them though.
I hope these 3 tricks help you out. The best thing to do is play around and try new things. I've got a lot of faith in you LR999, you'll put out some really great variants. ;)
