I just happened to stumble across the second picture when looking for "tmnt konami lcd" on Google Images. It seems to have originated from this patent, but the images don't seem to be available anymore for some reason, so I got it from a random topic at handheldmuseum.com where it was stolen from somewhere else.
In the released version, she seems to be "floating" further to the right as you can see in the posted video. Not sure if it's because the graphics layer was incorrectly trimmed or if the final graphics ended up looking bigger (or the background smaller) than originally intended.
EDIT: On second thought and after looking at the actual handheld rather than relying on pictures, those shadows may be actually cast by the metal pipes that come from the wall, so it would be kinda irrelevant to have April sitting on top of them...
