It seems that you draw rather short upper arms to your female characters, thus making the lower arm oddly imposant. Shoudlers at rest, the elbow should reach navel level approximately. Here it would reach the level of the floating ribs, maximum.
What the hell? You actually say that? how weird. So the danish invasions left some traces after all ... Anyway, you should probably say "leaking like a sieve" instead. Anyway, the name Siv has nothing to do with a sieve. I don't know much about it, but it has two probable origins. Either it derives from "Sif"(Nordic goddess), or maybe it's the plant. "siv", is used as a metaphor for lithe girls, due to the fact that it actually means soft rush(the plant).
