I THOUGHT I recognized him, when I read the description I had an 'aaaaaah!' moment. I love the walking dead :) and you're right, eye patches do rock. I like your linework, normally I'd say something like recommend paying attention to keeping the lines crips and smooth, but I think the rough linework works in the favor of this piece. If anything I feel like it needs some shading, it's like there's this strong light above him but no shadow being cast. Anyhow, great character work, nice framing, good work, keep it up :)
