Dude these guys are underpricing so much.
You have a firm grasp of anatomy, have clean linework, and have payed wonderful attention to detail. I especially love the Ezahnis o-o I'd say 5mil at the least.
How long do these usually take? You should factor a bit of your own opinion in to it. It's clear you work very hard on them, and you shouldn't underprice yourself. I don't want to sound mean, but a lot of users give you a price based on what they can afford (which is not much) =x
It's always your decision though, if they don't take long and you think a mil is a fair price... but if I were you I'd want much more than a mil. o-o
