Edgar Allan Typoes corrects: "Will I draw a completely new Kenshi and color that?" Constructive criticism will, oh yes, do.

Well, since you're aware of the issues with his proportions, I think the individual parts are fairly well done and that you should try out some more detailed shading. Though, if you're going to color it, then more shading with pencil would be pointless and I don't know how you are at shading with colors so I don't know how that would turn out, hehehe... Either way, I think it's a good job but if you're already aware of his proportions then you should find the patience to fix them as you go, however tedious it might be. As someone who draws nothing but people, I'm not exaggerating when I say I spend up to three hours just getting the proportions exactly how I want them sometimes. Other times I don't notice the problems until I'm done and it's a whole fiasco, but that's not the point...

Much appreciated. Yeah, I didn't feel like putting too much time into the details in case I'd be coloring it anyway. People often aim for perfectionism which isn't always a good thing in drawing art, especially if it'll become a burden that makes you leave drawing completely, as it has been for many. This is not your problem though, as you keep on drawing.
Okay, maybe I'll draw another one one day. Could you check "Scrapian" out as well? It's not exactly serious but it's unworthy by no means either.
