Challenge 48 is Issei Yoshino’s Manta Ray.
For an animal with few details, Yoshino’s Ray has a lot of details. He has gill vents on the front side, eye prong things on the head, and a knob leading into the tail on the back. It’s a really elegant and detailed model.
I must have made this one around the same time as the previous challenge, because I forgot to paint it beforehand and used water colours after. My pictures have one of the tricky folds near the neck stretched so that I’ll remember it if I want more rays. Too bad I forgot the trick to the gills.
