This scorpion is one of the most complex design I've folded but, it was not as hard as others I've tried; thanks in large parts to a great tutorial made by Tadashi Mori, the designer himself.
This is the first time I paint a model after folding, because I was afraid that it would add too much thickness to the paper if I painted beforehand, since there are many overlapping layers in some parts.
Although I would have rather not painted over it; the folds are still very visible and it does look nice like this.
The tutorial for this model can be found on Tadashi Mori's Youtube page. [link]
