She looks tall! Even if you took the picture from an angle that will give that feel, but looking at her legs, it tells she is about 6 foot tall if she were real. Awesome work!
Now that I'm looking at this again this kind of looks like a life size statue like something like four or five feet tall. But isn't this closer to the size of an action figure or a Barbie doll?
I think it is the image on the left that does the best job at misleading you to believe Power Girl is life size. All the object around her look in proportion to a life size person. You don't happen to have that image of Power Girl by herself without the other images posted to Deviantart?
As tempted as I am to go into my usual incredulous take on PG, I'm going to refrain this time, because I happen to have statues of both Batman (now with a broken ear - sniff!) and Catwoman (in her now sadly abandoned spray-on purple cat-suit and thigh-high boots!), so I feel obliged to let you enjoy this particular indulgence without me spoiling it for once!
So, go ahead. Enjoy!
