Further development of photoshop techniques

I decided to look at more advanced ways of combing images in photoshop. using layer masks and online tutorials i created the following image, using the same sunbed image seen in the pervious experiments as a back ground, along with images of women and images of electrical components.

The next image i was particularly proud of, as i managed to make my subject look more 3Dimensional and almost hollow unlike the one above where the object is simply lay behind the subject.

Above are the three images used (again all sourced on google)

Following a tutorial, and using multiple layers, and filter effects I produced the following image.
I think, the 3Dimensional intersection and hollowed out effect is something that could definitely be incorporated into my final piece, although I think I would keep it to a minimum, I particularly like the idea of placing it on the arm as I have done with this one.
