We have an awesome collection of Monster Portraits done in Zbrush by Idrassi Soufiane, a digital artist from Marrocco. These Zbrush concepts look so amazing even know they're monsters.
I think I have mentioned this many times already but I love how some individuals are crazy talented at drawing portraits that will come close to an actual photograph. If we are speaking of celebrities, you can practically easily recognize them. Let's take a look at the work of Robinson Cursor, he is an illustrator and typographer based in Budapest, Hungary. I just help to notice Arnold's portrait that looks totally badass. I am sure Robinson got inspired by the Terminator movie on this one, I hope you will enjoy the entire series!
