Given the recent song's release date and content, I'd say you're getting faster at video production.
actually this one took exactly the same amount of time as the previous, according to their release dates when compared with the previous. this is actually bad news for the most recent one because it should have had multiple advantages. it was much shorter, and it was already 100% written when i picked it. so the fact that it took the same amount of time (actually a few days more) is not a victory at all.
