I think this is the only time I've fav'd a Robin piece. Between his superhero name and (sometimes) costume, I often have a tough time taking him seriously. This piece, however, not only puts forth a seriously badass design--he LOOKS like a robin! I am impressed by this guy and can definitely see him fighting crime alongside Batman. Amazing job.
You're welcome. On coloring, it looks to me like using fully opaque black lines a bit for definition/cape folds/shading would help it look more polished. And if it's all colored via photoshop, this piece would probably work well with the magic wand tool for adding a background color if you so desired. As is, the actual color choices and reduced opaqueness for muscle tone all look really nice IMO.
