Two models designed by Robert J. Lang and folded by me from 2 uncut squares of kraft paper 23cm. I'm not a fan of RJ Lang, his models are usually very tricky to fold, but these two african animals are an exception.
I am not crazy about this lion model, however the Gazelle looks very nice. I am talking about the models here, not your work, you did an excellent job on both.
Does the gazelle have a color change, it looks as though the back legs might be reversed?
I agree with you about the lion, not among the best origami lions. They are both on the same book (Paper Animals by RJ Lang) so i just tried to set the same scenario of the book cover. The gazelle doesn't have a color-change. I used this kraft paper with a pattern of childish drawings (teddybears and the like) on a side and unfortunately you can see them through in some points. It's the same paper I used as a background on this photo [link]
