Keeper 001: License to Fill

This crossword began as a single clue (14ac), which gave me the idea for a fun themed puzzle. The finished product was a bit more edgy than I intended (more Private Eye than, say, the FT or Guardian). Apologies in advance if you are in any way offended. I'm a novice at this; no doubt I've broken some unwritten "rules" of cryptic crossword setting. I'm sure someone will set me straight.

 

Oh, I can post the annotated solution once someone comments here and requests it.
