Keep On Practicing, You're Getting There
The animation was for the most part smooth, but in some places it was either choppy or too smooth. Remember that not everything is perfectly smooth but lots of things are smooth to a degree. The blood was excellent, absolutely superb. The artwork could be better. The character design was subpar, and although simple character designs aren't necessarily bad, those seem to be way to simple. If you want to keep that style of character designs, add some better shading and other details to them and maybe when they jump and land their bottom could squish and un-squish. The background was extremely simple and needs some work. Maybe add some lighting or a more complex background to it. Remember: Shading is your friend. The sword and the grenade could use some shading and overall more detail as well. Once you choose a basic color you can use different shades of that color to make it look more detailed, you'd be suprised at how much better something can look with two shades as opposed to one shade of color. The AK wasn't bad, but it looked like it could do with some touching-up. The song went pretty well with the animation and was a good choice. Audio is extremely important in animations, and you seemed to have gotten that down. The effects (gun shots and what not but excluding blood) could also use work. Try to use filters (if you have Flash 8 or Photoshop) or use gradients and once again, different shades of colors. But remember to not go crazy with color, a good muzzle flash should be maybe a yellow-orange and orange-red color that mesh together well. I think I have covered everything now. Keep practicing and don't be afraid to try new things. Good luck with your future projects.
