Misha is his name if you follow the comics (which are pretty cool to read).
Anyway, I love the stab at minimalism especially with the use of only three colors. Understanding contrast and color is a big part of composition in anything. With minimalism, you don't have to completely go all the way down with details though. I would suggest using minimalism as a way to exaggerated important features of a character, their posture, and expression. As an example, exaggerating the basic shapes of his stern facial expression is a great way to use minimalism. You did do this but, and I rarely say this, it's too detailed. Translating his face into the most important sharp shapes might become more interesting. Take what I say as you will, I haven't touched minimalism for a while. Nevertheless, you're balance and posture is perfect to the character and I hope to see more from you in the future!
