Didn't take too long to get my hand in, so once I figured out what I was doing it happened reasonably quick (but not as quick as I would have liked partly because it's been a week and mostly because I have unrealistic and generally unachievable expectations of myself).
Decided to do the tail feathers by colour instead of individually and the barby bits are kind of painstaking because the brush is tinier than 3dC wants to deal with, but we're glacially getting there.
