I'm glad you reposted the images, I personally think there's room for your character in the Poser community even alongisde G.I.R.L. I know one thing that I find useful about the MilGirl mesh is that it loads fast, and can take any V1/2 textures, so those facts might work in your favor.

I realize the character wasn't intended as a commercial project, so I apologize if it sounded like I was suggesting you had stolen someone else's work for profit. Blackhearted's Nia is a great character, and I think you've complimented the morphs nicely. I hope the project works out for you, whether or not you decide to release her commercially. :)
