Hi, Ronan. Thanks for trying. Between the two samples, I don't think there's noticeable difference regarding the effect I'm looking for, though both are better than the original screen. But the problem is previous to your attempts -- the downscaled screen I posted is awful. It's those scaling artifacts I always get in my samples (especially noticeable in the brighter areas, the score display...), what will never let us get a good result, I'm sure.
Check this again:
Since I'll be using scanned art to illustrate every article, my goal is to get screens which look like they have been scanned from printed paper too, otherwise both forms just don't fit in with each other well enough. And besides, it's the only way I know to properly make small screens like these look both, real and nice.
In case you need more examples:
I though it could be a matter of focus and some texture, but maybe downscaling photographs is not the way, no matter what.
