for sasuke drawin - definitely there'z somthin wrong with the head, itz face not big enough (compare 2 the big neck and body) so itz feel awkward. Maybe coz u make the body by urself, but u try copy for the face

for robot drawin - bold the line and it'll look great, maybe coz I can't draw robot so I like tiz 1 best

4 the last drawin - remind me of terminator sketch
