I just felt an alteration or two should’ve been made: CUT ME SOME SLACK!
Usually that's something you talk about with the artist before she starts drawing. I have had people who negotiated being allowed to critique things. But I don't accept that kind very often. It's usually when they don't have good references or something. I rarely change things after I've finished the drawing unless I've made major errors that were my fault(such as getting the wrong eye color) or they are my actual friends.
