flandre? remilia?

According to the tags on Pixiv, it is those two, older.

I think Lavathein and Gugnir were pretty good clues; Hairstyles help too.

I like their original designs, pretty adorable most of the time. But this... this... ah, curves, nice things you can grope, I mean hold. Yeah, I prefer the girls a bit more mature.

And the contrast between the two is pretty well done. All the way down to the panties, good stuff

The Artist messed up with Flandre's wings, and Remi's are missing entirely :(

not to mention if they look like children and are like 300 years old... then now they have to be like some thousand years old... yikes...

that or they just transformed their bodies to look like that

Yeah, he totally should've remembered Flan-chan's christmas wings at least. Without them it just looks like a misc chick with a great ass.

...

oh, well:) Nothing wrong with that.
