ah, so that's what it is, the leg is actually folded back onto itself... for a moment there i couldn't figure it out, i thought it was on top of the other leg, which can't be as that one is right out there. silly me.
perhaps a tighter crop removing the folded part of the leg? (my screen happened to scroll and cover that part and it looks quite ok)
is it the low res that cause little splotches on the image? Kinda remind me of a shot by wee khim
