It's an interesting series but very uneven and while this technique could be used to say interesting things, it can also be used to mash together meaningless images to make a meaningless composite.
I think it depends on the component photographs. If these are uninspired and just feature models looking around the room without direction then the finished product doesn't do anything for me. If they play out different roles then the image becomes about something.
This is image getting there - I think because the styling works (the dress pattern does interesting things when blended) and the model is doing something interesting - her pose and expression of anxiety work together:
This one is quite boring - this guy does nothing for me. Except it's clear he has a bit of an attitude on about being asked to pose:
This one is interesting as a texture. The eyes want to unravel what it is:
I like the way the composition is starting to go into a cubist area here, although would be so much better if the model was a bit more intense:
Another bored guy:
Well executed but throwaway - it doesn't really say anything. But you could explore this idea more, different scenarios, different people:
If the model didn't run off the screen on the right it would help to frame her. But she isn't doing anything really worth exploring:
This one is simple and clean and grabs the eye as a strong composition so at least it succeeds on a graphic front but it still needs to have something to say:
More of the same. The first thing I think of is: Photoshop blending modes. After that I want to think 'but look how cleverly they are being used to make a subtle message'. But I don't think this - although you could certainly develop it.
So in summary: collage is worth pursuing, but it needs to really say something. Without that you are showing some fairly bland images composited using a fairly obvious technique.
