For me there quite alot of work of doin this also. I think can be done in photoshop but there is quite some tools u need to use to do it.

Filter > Distort > Shear (finish the pictures shear in another file first then onli put into the big canvas)
Drop Shadow
Dodge and Burn

of course layer is very important la
