These incredible photos appear to be of real animals, or even sculptures. They are actually paintings created by alternating layers of acrylic paint and resin. These are the works of Singapore based Keng Lye who says:
I started my first series in 2012 where all the illustrations were “flat” and depth was created using the layering of resin and acrylic over the different parts of the illustration. This year, I started on the octopus and it was purely an experiment; I just wanted to see whether I could push this technique to a higher level. After applying acrylic paint straight onto the resin, I incorporated a 3-D element in this instance, it was a small pebble for the ranchu and octopus. For the turtle, I used an egg shell for the turtle shell and acrylic paint for the rest of the finishing. The whole idea here was to give the art work an even more 3D effect therefore you can have a better view from any angle. I think there are still many other techniques to explore.
