None of them looks really sharp and are IMO not exposed properly.
They have chromatic aberration (green/purple fringes) that could easily be removed in Lightroom.
The second one has a fake sky color. It seems you replaced the sky, as the edge is too clean.
Hope that helps,

Thanks for your reply.
You can also try to replace the white sky with the Replace Sky command in Photoshop.
