Complex layering in Photoshop

So this is what I have been up to in the past week, it is very similar to what I have posted before regarding the Christmas sale frames I did in December.
However, this time I've got a bit more experience doing this in class and these are all my own original photographs.

 I've basically opened up a selection of photographs within Photoshop and then layered them all on top of each other. Then, using the different blending modes I kinda styled them as such to how I wanted them to look like.
It really isn't hard and it just takes time to investigate what the main tools are and what they do to experiment with them- most professionals don't know what every single feature within Photoshop does.
