average

Its not bad, animation wise.. even though I couldn't really tell what was happening.
But you need to make your name/title bigger, and stand out more.

lame

this "intro" is way too long

you need to make it less than 5 seconds

also NARATO SUCKS to most people so if you don't want people thinking that you are some retarded 4th grad kid, leave that kind of stuff out k

try using ninja giadon or something, y'know ?

cause narato is NOT a ninja

also the font needs MOAR DRAMA !!!!! OMG

not bad

but you might want to put a more dramatic font for your title, something that goes well with the action of the intro video itself

Quite nice

For a sprite video, that was rather well done! The sound and timing was perfect! Although the trouble is, an intro is always best followed up by a movie. Too short dude.

Cool idea, but could use some reworking

I get that you make "Sprite Vids," so I won't recommend that you improve the quality of the animation, but you might want to avoid zooming in. Because of the lack of detail in the sprites, the first few seconds of the intro look a little amateurish, rather than cool and professional. I normally like the color-inversion thing, but it didn't work here.

The second half was better, although the transition from a swarm of shurikens (I know they aren't shurikens, but forget the correct word) to a block of wood is a little random. The block suggests a sort of training session, whereas the shurikens imply some sort of enemy horde. The Street Fighter-esque combos were well done, but I'd recommend you put the cool-factor those combos provide to better use against some actual enemies. Finally, the whirlwind shuriken deflection might look better in a dominantly gray or white color. The brown was a little odd and made me think of Loony Toons's Taz the tazmanian devil, rather than a human being.
