Comment on Hero Knight by Rusty001

I suggest that you start making some decisions and pull a lot of reference together based on those decisions. You said that it's leather, but what kind of leather? are you thinking something like the stuff in the latest GI Joe movie? or are you thinking something more hand crafted like Lord of the Rings leather. zippers and plastic clasps or cross ties and metal rings? think about what your character has access to. What their skills are. Where they are or have been. Based off the rough back story you carved out, it's going to be more patchwork. A really rough form of street armor. Think Casey from Teenage Mutant Ninja Turtles. As for the sword, it definitely says more "ninja" and I don't think that relates with where you said he's coming from. Maybe he does have access to a sword somewhere along the way, but weave that into the story somehow and make it important.
Get lots of reference. Lots and lots, and start pulling from it your favorite most applicable parts. Detail is going to sell this and make it unique. Make your drawing big enough to allow for that. It looks like your current image is on a 8.5 x 11 sheet of printer paper. if that's all you have access to that's fine, but fill it up! let the full body fill up the page top to bottom, and show some expanded detail bits in the empty spaces. Art takes time. Try spending at LEAST eight hours on this. and don't give up!
