Well done for being brave and posting another image.
The right place for critique of pictures is in one of the sharing forums:

OK, ignoring processing, here's a photo that's tightly cropped into a silhouetted tree. Grey sky behind, hills in the distance have slightly un-attractive wind turbines, there's some dull green herbage and then some snowy orange grasses. Lighting is dull & flat, and the image as presented looks slightly out of focus (possible camera shake?).
What I'd suggest first is that under the conditions as presented, it's really hard to take a conventional landscape image that looks good. There is nothing charming or exciting about dull lighting for this type of image, and no amount of processing can change that. Go back & re-shoot the scene when the sun is rising or setting, lighting the scene with a lovely warm glow from low down.
Composition-wise, we can't tell it's a lone tree because it fills the frame (possibly wisely, because the landscape behind appears unattractive) and in a picture like this the tree needs room to 'breath'. If you were to go back & re-shoot this is good light or when there's interesting/moody clouds behind, what I'd suggest would be either to use a longer lens with a wider aperture from a low angle, to frame the tree against the sky and hide the wind turbines, OR go in closer with a wide angle so that the turbines become much smaller and less obvious - and allow the tree lots of space in the frame.
Finally, make sure the picture is sharp *unless* it is meant to be blurred/soft. Use a tripod if you need a longer exposure than is safe to hand hold (rule of thumb: shutter speed should be higher than 1/focal length of lens, i.e. 50mm lens then use 1/60th as the slowest speed).
I really hope that's helpful - I don't want to tear your picture to pieces, but I do want to help you take better pictures.

Have a wander through some of the landscapey bits of the site, comparing this picture to those posted by others and see what you think:
