I am quite the fan of Predator. It was by far one of the best movies made in that time. I am overjoyed to see a perfect rendering of him in all his glory. I am especially happy to see that you drew him without his protective mask, therefore showcasing his true face. I like this artwork so much that I was inspired to actually made my own version of this, nowhere as good as this but still an attempt. The shading is truly exquisite and the eyes look truly evil and malicious.
A truly fantastic job on your part...
