While I often produce images like this one, well, every once in a while, I rarely post them as I'm frequently dissatisfied with the results. It's rarely a technical problem – I understand the techniques well enough – but more to do with the fact that I lack any clear aesthetic goal(s) when producing them. As such my attempts often end up looking like I layered a random collection of images just for the sake of it ... which never looks good.
Anyway, on this occasion I did have a good idea about what I wanted to say, and how to put the images together, and I'm pleased with how it turned out.
You may have noticed that the 'show the original' link is missing for this one. This isn't because I used multiple images, but because I thought it would be interesting to ask you how many originals you think I used to create it. So feel free to speculate, both about the number of originals, and their content, and let me know.
Finally, if you're interested in learning more about working with textures, take a look at my Working With Textures tutorials (details about part one here and part two here). Both were co-written with Mike Regnier and, if you take a look at either of his websites, you'll see that he's a whole lot better at this than me. Well, most of the time at least ;-)
Update: I've now enabled the 'show the original' and, as you can see, I only used two images to create the final version :)
