Well, because smashing things with your hand wouldn't be very princess-like =O
Smashing things with your hands can hurt a lot, even if the things are small enough to squish. A needle might be small in comparison, but it'll hurt like hell if you try to punch it.
On the character: The design is nice, but her thighs seem to be up to some mischief.
I personally like the second image, where she seems to have slightly longer limbs. It enhances the sense that she's huge, because her proportions play into the theme that she's more like a walking building than a human in terms of scale.
Look at Gaius for examples of this. The head of Gaius is tiny in comparison to his body, and it makes him seem even larger. The arms are longer and the legs are more like pillars than organic shapes.
Beware of her arms becoming too short, as it makes her look "stumpy", and not massive as she actually is.
The crown on her head could perhaps be made slightly taller, once again to accentuate the height of her. As it is now it kind of "cuts" her off at the top.
Depending on what her personality is like it could also pay of to be more direct with your strokes. Once again the second image is (in my opinion) better at this than the later ones. She just seems more powerfull and it works with her size that she moves with pretty much unstoppable direction. She could still be very careful if that is what you're going for, but there is weight behind her movement that is just colossal.
I also look forward to see what you do with perspective. I'd love to see you show some extreme angles and play with how enormous she is.
Must say I really like the idea, and look forward to read your stuff.
