Welcome to the forum. You will find the folks here eager to help, sometimes it may seem a "rough", but they are here to help.
My first impressions of your three images is that the important part of the landscape, the land, is underexposed - there is little, if any, visible detail - the third one is better than the other two, but is still a little underexposed. If you shoot in raw mode, then these can be improved by adjusting the exposure and maybe a little dodging of the underexposed areas. What you can do to try and improve these images depends on what "post-production" software you are using in your work flow.
It would also help reviewers if you could number your images as this makes it a lot easier to refer to them. Thanks.
