Excellent L911. I love the wall's texture and obviously the blend.
The hands on the sidewalk throw the perspective off with a different angle. If the overlapping images change angle, bend them a bit to somewhat match.
Another fun thing to try while squishing layers together is, make an additional layer of her and erase all but her arms, leaving shoulders dowm to fingers. Place over existing layer of same and add dropshadow. Now, eraser tool again and set FLOW to about 30%(on toolbar) and tool size about the size of her head and erase edges and mist top from shoulder area down using the outer edge of eraser tool.
Final outcome is her arms will appear 3D coming out of the wall.
Maybe I'll throw up an example later, but I know you'd have a good time with doing stuff like this.

WOW THANKS FOR THE TIPS $TYLE :) I HAD BLENDED IT DIFFERENTLY WHEN I STARTED AND THE MOD HAD BETTER DEPTH BUT LOST IT'S GRUNGY CHARM IN THE PROCESS. I WILL HAVE TO TRY THAT LATER, I WASN'T SURE IF ADDING A DROP SHADOW WOULD WORK BUT I DIDN'T EVEN THINK OF ADDING TO A SEPERATE LAYER. THANKS AGAIN :)
