The sky area looks a little better...not sure which tool you used exactly - I would choose the 'blur' tool (looks like a teardrop) over the smudge tool for doing this.
But in this image you also have some haloing/artifacting. See those white lines around the silhouette? Those will get you rejected (particularly at shutterstock). Those often come from sharpening. Sometimes you can get rid of those if they aren't too bad with the blur tool set for a very small diameter (and maybe between 30 and 50%) and running very carefully along the white line.
My personal opinion is that I'd still be a little concerned about the sky, and it's difficult to tell about the focus from you've posted - I don't know that it would pass shutterstock, but it might on bigstock photo.
I've run the blur tool at a diameter of 5 and strength of 60% very carefully along the white halo in your pic (still see a couple of areas I've missed), and the result is perhaps a little better, but my overall suggestion would be just reshoot a similar image, unless of course this one is something unusual that you can't do again.
