Help needed with texturing a photo

Fellas I hope you guys are doing well. I was going to start a new thread here but figured I'd just jump on this one. It might be a bit relevant in regards to photo editing, so maybe you guys can give me some suggestions.

I have a high resolution image for an event we're promoting. The theme/title is "Breaking the Mold" I had a hard time thinking of a concept to go with and have sketched a few things out.

But I really want this to look like a movie poster or a game cover. Anyway the conference is, from what I'm told is to deal with leadership and breaking the way things are normally done.

So I figured I'd try something like a guy kneeling or standing in a business suit, tearing his coat off, like a Superman type deal, but have only half of the image as a statue, while the top half is the man breaking out of the mold (so to speak).

So my question is, once I find a suitable image, how can I take a textured image or background and lay it over the man's body to make it look like he's in the mold itself.

I have thought about creating a brush with the texture and painting over the man and setting layer effects to "pin light" and setting opacity. While this works with paint pretty well, I figured it might work with texture.

But how do I create the brush with the texture for a high resolution image?

Now after I crop the man out of whatever background he's in, and I take a complete huge picture of a statue, plaster, broken concrete, can I just lay it over the man. Because I've tried it with a quick sample I had as a test and set the layer settings to all the ones on there, but the concrete would not wrap around the shadows, and highlights well. The texture would remain flat and not have depth of the man's body.

Any ideas as to how to accomplish this? I would greatly appreciate any help. Thanks for your time, look forward to some suggestions.

Cheers!

Hey zerimar,

I've put your question in a thread of its own, I figured you would get more response this way.
