I feel like Attack on Titan is a difficult series to draw art for, since there's usually a lot of motion involved, but I think you draw scenes from the series really well! The rough, sketchy lines in particular are very fitting. Overall, I enjoyed going through the pieces you've posted here. I'll be keeping an eye out for your work in the future, that's for sure.
( That animation at the end is mesmerizing, by the way. I don't know squat about animating figures but I can see the action clearly, and the frames appear to slide by smoothly. It looks great :-] )
