Designed by Fumiaki Kawahata, folded by me from 1 uncut square of kraft paper 23cm. I finally found black/white paper but it's too soft and doesn't hold the creases well. However the panda turned out not so bad.
I think your panda turned out very well, at least to the time of a picture. If you worry that it might not hold it's form very long, you could always "paint" it with CMC, that should help a lot. Of course, it's a long process, since you can only do small parts at once, to not lose the integrity of the model and ruin it but, I find that it helps a lot to keep the model from falling apart after only a few weeks (days in the worst cases.).
I like the color change on this model, it makes a big difference since the colors lay where they should. I wish That Mr. Kawahata had found a way to make the cheeks a bit bigger and rounded but, it's hard to find any other fault in this cute model.
