1 Poster... in layers
Actually some layers seem to be missing in the screenshot... O_o *scratches head*
Anyways, that's a good way to show that Photoshop isn't always click and done and not everything can be fixed with one layer. Especially when it comes to 50% non-painted art, I found it very useful to carefully layer effects over each other instead of trying to stuff everything in one.
Since I've got the bad habit of NOT naming everything I can strongly advise to NOT follow my example. ;) It's pure madness but in the workflow I totally forget resulting in massive swearing afterwards.
If somebody wonders: I work with both the English (home studio) and German (studio) version. Results in pretty funny files.
