Hello,
1) Please add this code in custom.css file:
.header{
margin-top: 10px;
margin-bottom: 10px;
}
2) It would be better if you uploaded the images the same size.
3) Please add following code in custom.css file:
.items-slider{
margin-bottom: 00px;
}
Also you need to remove some row via Visual Composer plugin. It creates extra space. See screenshot: http://prntscr.com/6npfpr
4) Please add following code in custom.css file:
footer a{
color:#787373;
}
Here is a video tutorial how to create custom.css: https://www.youtube.com/watch?v=Qok2zRedRMY&feature=youtu.be.
