 I think you already tryed to make it via the setting of Krita yourself, as I know you are talented at brush creation. 

But here I tested too and obtained that as a result :

Maybe it can help for the moment.

Thank you very much, but... ^^

Here's my personal preset!: http://www.mediafire.com/?guft2jij08lmy9u

(Tested on a canvas of 6000x4000px with the zoom at 25%)

It's very similar to the Opencanvas brush, but the brush color doesn't pick a little up of the nearest canvas colors with a sort of "trail" effect.

It's a smudging, not a colors mixing... This is the limitation of the actual brush engine imho.

[13:35] <plassy> [...] but to make it really look like the mypaint smudge i need to do some coding work... seems like mypaint doen't really "smear" the color, it's more like dulling it
