This is something my lighting mentor warned me before I designed my first show. She said that every beginning designer she had worked with never puts anything at full right away and makes timid design choices. While I had vowed to put things at full, a handful of cues in on my first night, I caught myself with most of my illuminated fixtures at 25, and fixed it.
Be wild, be crazy, don't be bland. Confidence is attractive. R54 frontlight makes for happy parents, but is rarely* a statement.
Congrats on your first show, which show is it?
* I can think of ways I could argue it as a statement, but just for example's sake...
