Very interesting, Amiable! According to that, a very short cut is not the best for me. I am like Imogen with 6.5 cm from ear lobe to chin, and my eyes aren't particularly big.
It sounds like I may be on the right track with what I'm envisioning. Like I said, none of the pics are The One. I think if I could combine the bluntness of #1 with the length of #5 and the roundish shape of #3, I'd be okay.
Maybe need another name to refer to haircuts between bob length and pixie length (perhaps this exists already and I just don't know).
