I noticed something wrong with the mod I did for the PJ; on the pants, the beige is showing through? :/ How do I fix that?
Do you mean when sometimes the pants/boots revert to default beige? I actually wondered if I should mention that, since as far as I can tell modding right now is not about bug fixing more just experimenting. But it happens a lot regardless of what color stuff is supposed to be. For example on one of my rogues the boots revert from great bear dark brown to beige randomly until I reload. And that's without mods. But I recently applied a modded pj and even though the whole is supposed to be black the pants and boots on the mage still revert to beige often.
Perhaps that's not really what you meant but if you did - I don't think you should worry about it since it's a bug (I think) that may or may not be fixed in the future for good and can be temporarily fixed with reload. Anyhow it looks fantastic and will probably end up using it too in the near future. 
On a side note I really like Denise's qunari female outfit so far! But as SheWildWolf said, the pants show when you're a mage. Someone may want to use blue or other colors when crafting, so a more neutral coloring at least for the metal parts would be a good idea in my opinion. But if you really weren't planning on sharing and you're just feeling generous, I get it if you'd rather not fiddle with it. It still looks awesome anyway.
