I am not a fan of tagging pages with {{refimprove}} as opposed to using {{citation needed}} tags, unless the page has very obvious and extensive issues with references (or BLPs). Refimprove tags are, in my opinion, quite ugly and unsightly things. They also make the page content start later and take up much space. Citation needed tags on the other hand do not take much space and are also more specific.
Use italics for the titles of works of literature and art, such as books, pamphlets, films (including short films), television series, music albums, and paintings. The titles of articles, chapters, songs, television episodes, and other short works are not italicized; instead, they're enclosed in double quotation marks.
