I started with this cropped and scaled image from a House screencap:

01. Duplicate base, leave at Normal 100%
02. Delete original base; this will leave just the copy.
03. Erase the background. When that's done, you'll have an empty (transparent) background, like this:

04. Duplicate the base, set Screen 100%.
05. Duplicate the screen layer twice, leave Screen 100%. There are now a total of four layers.
06. Duplicate the screen layer, set Overlay 100%.
07. On the Overlay layer, erase everything but the face.
08. Duplicate the Overlay layer, set Soft Light 45%.
09. New layer, 94ceed, set Burn 50%.
10. Duplicate base, move to become top layer, desaturate, set Screen 100%.
11. Duplicate 94ceed layer, move to become top layer, set Soft Light 40%.
12. New layer, ffddcc, set Multiply 50%.
13. Duplicate desaturated layer, move to become top layer, set Soft Light 50%.
14. Now we add the background. Add this texture

leave Normal 100%.
15. Duplicate new base layer twice, set Screen 100% on both.
16. Using white, apply brush #7 from this set by

the layer third from the bottom. The majority of the brush will be behind House.
17. Apply texture

become third layer from bottom. I also adjusted the layer so the bright star was more over House's shoulder.
18. Merge layers being sure to clip to bottom layer.
Here's my Layers dialog at the end of it all.

I love feedback, and I'd love to see your results!
