This is one of the best drawings of older Ezio. You’re talented in making assassins more self-confident. It's difficult to explain . Most of the artists draw Altair or Ezio in some kind of sweet way, without expression. You gave our protagonist powerful expression, maybe I see what I want to see, but I see (as on Altair drawing) a lot of arrogance in Ezio face. And that how he should be like. Not a sweet guy with hidden blade but a really tough guy. A soldier.
This is really a piece of art. Your Ezio and Altair in this picture are really great. So dark style, maybe they remind me a bit of Angel Sanctuary...Two angels of death.... This could be the perfect title for this drawing
