Well, the first step is to take a suitable photo of a whole bunch of pink and white balloons. Have you done so?
But gosh, even if you take a perfectly-assembled, perfectly-lit, perfectly-angled photo of the balloons, the translucent bits of her skirt are going to be demonically hard to mask.
I'll be offline for a while, I'm afraid.
Try a Channel Mixer layer:
Red 0, +85, 0
Green 0, +100, 0
Blue 0, +130, 0
Fiddle with those values and see if you can get close. If it's not good enough, I'll be back to check this thread later.
That stops TODAY. Have some pride in your prints.
Now that we're looking at the 100% crops, can you see the problem?

Yeah, this is all wrong. You can't just upload uncropped, unresized, unsharpened files, and expect them to print properly.
As I said earlier, your 8x10 print jpegs should be (usually) between 500KB and 2MB.

I don't understand the problem? Click on the jpeg files that you uploaded, then show me those same properties screenshots. Showing the file size, the dimensions, and so on.
I very much fear the angles won't work. I'm trying it, but the angle is implausible. Nobody would naturally have such a flexible neck that they could turn their face so directly to the camera when their body is so side-on, if you know what I mean.
