I just realized, anthro Barb is basically an argonian. Which means…  
Time to get lusty.
 

There is enough variance here with there normal forms that there could be a bunch of stories between them as it, and it would just be a start.
 
And I love that you are basing them on Spike and Rarity, it doesn’t need a complete overhaul to make their genderbendered forms work. I have to wonder, if this is gonna be a more permanent presence there has to be more genderbended characters. Also I adore that they are gradual changes but at the same time they Elusive and Barb are distinct and different from Spike and Rarity.
 
Long story short, I adore it. Can’t believe that you say that it’s just a draft, it seems like it’s ready for print!! Also, put some clothes on them I would love to see this version of Barb in a dress, or what Elusive looks like in a tuxedo. And of course, it’s gonna have your wonderful touch all over it!!
 
Please, more!!!

O_O
 
All of my yes!!
 
This should be a comic, i would read the color out of it XD

Come-on Elusive, give Barb the touch she so desperately needs.
