This is an absolutely amazing piece of work. What is particularly effective about this artwork is how his eyes seem glowing; the whiteness of his iris symbolise how his mind is becoming blank and empty. Another concept of this piece which I found interesting was how his glasses, which tie him to his identity as Simon Petrikov, are cracked. His hand is outreached towards them, as an effort to hold on to that identity. This really matures the transformation from Simon Petrikov to Ice King into something that is more haunting and sinister than it is first portrayed.
This is truly amazing. I just love his pose and his eyes. I actually like that you didn't put any color in because it represents how cold he looks and feels. I wish I was this great of an artist, but, that time will come. Your time came already, and it came just at the right time for you to draw this. You are a great artist, and I hope you are able to make more of this wonderful artwork soon. I know it will be great. (I can be a very picky at times, but you reach all of my expectations.)
