My favorite character in AC3. Love love love him! I don't have much reference to go on, and don't know if you guys notice, the in game model has a ridiculously long face... I wish I didn't change him too much and he's still recognizable as Haytham. I also hope, I captured his determination, resolve and charisma.
On the technique side, I try to do this in the old Gilbert Stuart style, I figure if Haytham had his painting done, could be by Stuart. LOL. didn't quite get it though, but I tried.
here's the painting process: [link]
Also, I'm not familiar with various fan groups, so if you know any good groups that might want to add this work, please let me know.
