I thought it would be too self-indulgent to have a self-portrait, and I'm never really happy using premade ones from well-known series, it sort of feels like an admission of adherence to herd-mentality. There's also my complex about copyright, therefore for totally irrational reasons, I shyed away from using a random image from a search engine.
So, I used a photo I took of a statue at a local graveyard... so now rather than being self-indulgent, ultra-conformist, or legally infringing, it's just plain ordinary pretentious.
