This is an absolutely stunning piece of art - the look on Ezio's face is so mesmerizing that I spent several minutes studying all the little details. The dark intensity of his gaze, the lines on his forehead and the light in his hair. It's really hard to find the right words to describe how much I love this.
Best thing of all is that it perfectly portrays the love Leonardo (and you) put into the piece.
It's been on my favorites list for a few days, but since I have come back to view it a few times since adding it, and because it deserves the praise, I decided to post.
