The work of customizing may require meticulosity. You can change many sections and all of the custom features are in the Customize.
Firstly, you have an add unlimited number of the slider for the homepage slider in the Thinkup slider section. You can even add the title and URL to the slider here. There are even 2 styles for the slider: full-width and container style. And the height of it can be modified up to 500 px. That's such a good way to diversify this area.
Customizing slider
If you want other styles for the slider, there is a Custom slider section require knowledge about coding. But I'm a blogger, not a developer so I don't need to use this section. Additionally, this slider can be disabled.
The featured area has at most 3 posts. I think that this number is adequate to perform your most prominent posts here. I test 1 post on my WordPress blog and see that it's easy to set up this section.

To add more elements to the header, go to the Header content and here you can control the Search tool and Social icon. They appear on the top bar and are distributed logically to fit with the design of the header.

There are 6 most common social networking site and 1 custom URL in the Social Media Content. You can carefully style the social icon by using the default or uploaded image.
Customizing social media
From my point of view, besides the designated social media, I need to add other sites. And 1 custom URL is not enough for me to connect my readers to my social sites.
The style of the whole site can't be changed but you can modify the sidebar position to the left, right or even no sidebar. There are the sidebar options for the homepage, blog page, and single page. On the blog page, you can even control some option to make it fit with your purpose.
Customizing layout
The most unique thing I find in this theme is the footer style. There are numerous styles for the footer column, the feature that I thought only the Premium version possesses. Such an amazing thing you can do to your footer columns. All the styles can be applied and every basic widget of a WordPress blog theme can be rendered properly here.

The custom color is restricted with only 2 sections. Yet when I change the header text color, it still remains black. I couldn't find any part that turns into green in this blog.
Customizing color
Like almost every other blog, you can choose an image as the background and select style, position and size to make it fit with the whole site.
Next, the header image is another choice to personalize your WordPress blog. You can crop it to any size. But I find the display not really attractive. I think that the title should be on the header image to make it look reasonable.
Customizing header image
Other elements like typography, blog structure are fixed with the default style. But I think it's good for a minimal blog so you don't need any change.
