I am going to ramble a here a bit . . .
the first image is emotional, you can feel the solitude to the point it is almost painful. The second one, while compositionaly better, has no emotion. It is an abstract piece that requires an interpretation.
Rearrange the first one a little and keep that empty surrounding part of the image in there. Mask off the tree and increase the contrast and exposure on it (get it to stand out from the ground a little more). It's hard to tell without trying few things, but it is a nice shot now and it could be a show stopper with a little bit of cleanup.
p.s. just my opinion and it's worth every penny you paid for it! That means not even the $0.02! but I had to throw it out there. Hopefully no offense taken. . .
