It's not really working for me. Vineyards are ever so tempting, but I've never been able to make much of them. It's like photos or graffiti or abandoned buildings, one feels there ought to be an image in here, and a darn good one, but everything one shoots is just junk. This isn't junk, per se, it's a jolly good effort at a hard subject, but I can't find anything to love in it.
In the original, the wires in the background are a bit jarring, and the crop is simply too tight for me.
If you don't want to give up on it, try a less harsh contrast. This sort of subject seems to to well with a softer more pictorial feeling, and maybe you can go someplace good with that.
