this one's pretty nice. I like the sketchyness of it, too.
heh, and a critique 'cause you'll probably yell at me if I don't.
The upper arm is almost twice as long as it should be, and the angle of the lower arm to hand to sword is a little awkward. That right leg is also a little funny, is it supposed to be bent? A little shading in the right spots or even just a creative use of contour line could give that effect.
I like the amount of detail, and the sketchy look you gave this drawing is very nice.
aaand because I'm a blockhead and forgot to write it in,
Changing the position of the right foot could also do wonders for giving the impression that the leg is bent, right now it's in the wrong position entirely it's also a little small, so when you take perspective into account it looks like it should be way off in the distance. in which case his leg is super long and he's about to fall on his tail end.
