Hey, this looks like a cool armored version of Joan. (lol, like she wasn't armored enough. Try working out some smoother lines. Don't be afraid to use the eraser to smooth things over.
Yeah, I was gonna say something similar. I'm used to seeing rough bold lines for things that are moving, it really makes things look kinetic, like a fierce action punch. Another thing bold lines say is that the image is complete or in its final stages. Like sketching on paper perhaps leaving the inking till the end will help your work flow.Your progressing fast with these digital sketches by the way.
