My custom Ui kinda looks the same . Only difference that i have grid and decurse positioned where u have the guild tab chat ( in only use one tab).
you can try and find the MiniMapButtons addon that let you group all minimap buttons in one so you have a clear minimap .
I also use quartz which is position at right and bellow where are your DBM announcing bars. And Auracle custom buffs /debuffs positioned same
