Your room reminds me of Peter Lawrence's place ("The Happy Minimalist")
I personally find your apartment to be a little stark, but I'm not sure if it's because there are so few pieces or because it's trying to be a drastically minimalist version of our culture's aesthetic. To bae's point, it may simply lack a little feng shui. Rooms that I absolutely find peaceful in their simplicity tend to be Japanese-style--with very calculated use of natural elements, light and architectural detail to bring balance and harmony to a minimalist room.
But, you have a right to be proud! You are living your values and truly walking your talk. I'm impressed!
