I'm really digging Arian Noveir's series Super Heroes Painted. Arian captures the essence of each character with some well placed paint splatters and shapes. Each one has a great unique look, but also fits in well with the series as a whole. The paintings look minimalist, but give away enough details to clearly see who the character is. If you like these, you can get the prints on Society6.
There is one thing all great presidents have in common: being a badass. Jason Heuser (SharpWriter on Deviant Art) perfectly portrays this concept in his awesome presidential portraits. This series has everything from fighting robots, zombies, and gorillas to riding a grizzly bear to victory. Make sure to check out his other paintings on Deviant Art, he some truly great work.
