Oil Pastels: Poison Dart Frogs

My latest attempt at oil pastels.  These were quite fun to draw; I'm really enjoying using oil pastels.  Clockwise from top left: Blue Poison Dart Frog (aka Okopipi), Bumblebee Poison Dart Frog, Strawberry Poison Dart Frog (Blue Jeans Morph), and a Green and Black Poison Dart Frog.
