Yes, it does look a bit 'painterly'. I would suggest this is not only due to the smeared sky but the overly saturated colors. I can't quite believe that barn roof is that red or the grass so green.
We've got so used to modern painters exaggerating colors in landscapes, and sometimes producing completely false colors, that this has now become a trade-mark of paintings.
Producing out-of-gamut colors on a print also reduces resolution, which contributes to the painterly effect.
By the way, a criticism of your image would be the excessively dark foreground at the bottom of the image. I don't think this contributes to a painterly effect. I think a painter would want to put more detail there, or perhaps you could crop it.
Nice image, though!
I think I might prefer this. But it's very subjective of course.
