I actually like the filter in a general sort of way. It would be nice if you could maintain the "abstract" quality of the photo but sharpen up the lines. It would make it look something like an old etching. Also, fade/chop the edges; it looks like a photo over a scroll right now, but with a little creative work you could make it look like it was on the scroll. My next comment is in the same vein as the last one, either enlarge the scroll or shrink the brewery name (and get rid of the shadow) so it also looks like it's on the scroll (the same goes for the hops and date on the bottom). Finally, I would bring up the wheat "tops" (I'm not sure what they're legitimately called), you could use them to frame the bottom of the image and they could also be made to look like they were "on" the scroll.
All this might be too much, but I like the concept and I started running with it. I guess it turned into more of a "wish list" than appropriate constructive comments.
