1st- Needs more frames. Other than that it's decent.
2nd- More frames and work on movements. Also, the lines for the background are too thick. My favorite part was the last little hit thing through the wall.
3rd- Decent. Animate the reaction, don't just animate half of one reaction and have him stop suddenly.
Well the fact that arch angel said your work was decent meens that you must have improved alot. Well done bud. Although seeing as i am currently on my phone i wont be able to check them out until tomorrow. (:
Ok I finally got the chance to see them, and all I can say is holly shit, you got better. I have no idea how you got so good so fast, but you better keep it up!
