As you can already see and will see in more images below, this isn’t fully an ICS look. The status bar icons are different and he opted to not follow suit with the ICS styled lockscreen. I applaud the dev for that maneuver. He did include the icons and tweak a few things out that are rather pleasant on the eyes. I think it is an extremely well done theme that deserves your download.
Status bar icons will not change. This is not to be a direct take of ICS, it is my interpretation. The status bar icons in ICS are ugly in my opinion. I will try to theme the contacts to match the people app but that is going to take some time as mixing dark and light themes always are. As for the clock color, that is directly from the dump so I am not the person that made it. I will likely add some glow to it in the future.
As with any MIUI theme, you will want to download the mtz file and move it to MIUI/Themes folder on your SD card. Since this is a full theme you can find it in the themes app without the need to access the customize section. If you are only interested in certain parts of the theme though, feel free to mix and match.
