My arm isn't done, and I've only really started on one, but I can actually contribute! So I shall. :) Taking pictures of my own arm is hard, and I suck at it. There are individual pictures of these in my gallery, though, anyway!
I was really late in coming to an appreciation of traditional designs (aside from traditional Japanese, which I have always loved). What sold me on traditional sleeves was the interesting way in which individual pieces become more than the sum of each individual tattoo...it becomes this collective aesthetic that I find so fascinating, in addition to being a very cool collection of individual images.
I mention this because I have similar feelings about 'masculine' and 'feminine' aesthetics. (I'm also one of those people who thinks a man or woman can wear whatever the hell they want and still be masculine and feminine if they want to be, but that's a discussion of a slightly different variety. For the purposes of this post, I'm just using the generally accepted definitions of those words.) I think whether something reads as 'masculine' or 'feminine' in the traditional sense depends mostly on general presentation. There are tons of pictures out there of women wearing tough, aggressive traditional work, but they dress or present themselves in a way that's still super-girly and feminine. I think this look is amazing.
Of course, there'll always be people out there who just find tattoos in general 'unfeminine' or whatever, buuut. That's really more about them, imo.
