Mukhin has decorated numerous churches in the US, Malta, Croatia, Serbia, Japan and Russia. From 2014 on he worked for the mosaic compositions in the St. Sava church in Belgrade, which had seen realization from 2017 on. They will be completed in late 2020. His competition entry was chosen from among approximately 50 competitors. His proposal was described as: "the artist uses a specific iconography which reaches back to the Byzantine and Serbian art and creates compositions which redefine the interior of a modern sacral space".
