Need advice about a FAC review 

I need some advice. I reviewed and opposed Wikipedia:Featured article candidates/St. Michael's Cathedral, Qingdao/archive3 yesterday. The nominator is pushing back and spilling it over to other pages. I would like to remove myself - how is that done? Can I strike all my comments?   FWIW, from the books I found with a quick search, I stand by my opinion that the article is not comprehensive.
