Just an example. A more advanced free alternative to Photoshop is GIMP, which is basically as advanced as photoshop just with a tad bit less features, and definitely has a large amount of filters and effects. My point is, even free alternatives as simple as paint.net can do this stuff.
Granted this isn't the same style, but paint.net is quite ground down and only has 3 effects in the "Artistic" category. I'm sure GIMP can make something almost in the exact same style.
Oh.. Well I used a different tool in here and what I did was not just a simple filter. Anyway, I'll just lock this topic now, Saying that it's as simple as that then maybe others can do it on their own so no need to provide a service like this. Thanks for your time tho mr..
