Okay, have to join in on this one ^^
I made this in 2013, and it was the first time I felt like I was starting to get some kind of grip on how to do skin colour. I still think it's difficult to get right, and there are things about this image I would've changed when I look at it now. But I remember working on this and seeing as it slowly got better, and when I finally decided I was done with it, I was more happy with the result than I could remember having been in a very long time. It's quite simple, because I wanted to be able to focus on the skin and not worry too much about other things. It's a depiction of Huldra ^^
And then there's this one:
I used a stock photo by SenshiStock on deviantART as reference for the pose and angle. I just really like the idea behind it, and I've been planning to do three more images like this with different colours, but I never have time to get around to it.
