They look decent, really! Just one thing (which is probably on the cuastomer side, anyway): be more careful with images - I see multiple in sizes 300 - 500 kB, which is a killer in my book, especially when using a slider.
Could you also please expand a bit on to what extent it is a Couch (that is, only defined editable regions or menu-maker, relations or even mosaic, etc.)? Specifically, I wiuld be wondering how you are adding the fa icons in the Our Services section at traktor-sp.co.id. Are they hardcoded, or are you somehow allowing admin selection?
