Sorry for taking this long to reply, I'm always like ''I'll reply this later'' *proceeds to completely forget about it*... :s
Anyways, once again thanks for the critique, I kept the line variation in mind, when I was working in my latest drawing, the bloodborne hunter (down here :p), but I noticed that I tend to skip the line quality when it comes to drawings I know that I will paint at some point, maybe I should keep that in mind even when it comes to full colored works.
PS: Sorry for any grammar errors
