That's a great looking character!  Her bone structure looks of German ancestry, so I'd go with a light skin colouring.

I just found out a little while ago about the camera focal length. I had been using them at default and for some reason one day I was working with a figure in face view and her head looked oddly shaped. I hadn't noticed it before so I asked about it here and sure enough found out that default cameras aren't optimal and was given the recommendation to change all my camera focal lengths to 105. I've noticed a marked improvement after doing that.  Took a bit of time to get used to after seeing distorted images for so many months,  LOL

Great work on the character, I can't wait to see the finished product.

heart whatever they might have to say." - Ghandi
