..Well, since its better not to make a new thread just to ask people to criticize my Ness, I think I'lld just post my videos here.

Sorry for the bad quality, I don't have a capture card... yet.
Yeah... that Fox wasn't that great. All he did was spam his smashes! (The only time I saw that he used a tilt was at 0:23 where he used a dtilt

). You can try punishing smash-spammers with you tilts, since they are faster. Which brings up my main point... You didn't use any tilts either! Ftilt is pretty fast and has decent knockback; you should definitely use it. Also, you never really used much of your smashes... You threw in the bat a few times. Ness' yo-yo is very good to use when your opponent keeps just dodging around you.
Second, between 0:55 and 1:24 you were getting completely owned

. You just kind of kept jumping around...

. You kind of overused your aerials (although Ness' aerials are very nice). Once again, just try and use ftilt/usmash when he is in front of you, or dsmash when he keeps rolling behind you. You used you jab nicely, although he might not know you can shield the third jab. (I'm pretty sure you can.) The other thing was during that sequence you kept doing normal PKT2 to recover, which left you really open. Try watching Ref's PKT2 video (
http://www.youtube.com/watch?v=-lpdm8wgSNg) to see how to use it more effectively. A lot of the times you didn't even need to PKT2; you could of just air dodged and grabbed on to the edge to recover.
Lastly just do what Uffe said. Your friend was very predictable with what moves he would use. Fox is very light, so bthrow kills at around 110-120% on him. Try using some retreating fairs also (Short Hop --> analog stick going backwards stick going forwards). This will help with some spacing factors. What I find that also helped my Ness game a LOT was EB360's guide, if you haven't already (

.
EDIT: Forgot to watch the second video lol.
Basically the same stuff though.
Less Bairs
More Tilts
More Fairs
More dodging and shielding
You had a nice bair chain into a dair at 1:08 (Too bad it didn't kill >.<).
You can really take advantage of all of his smash spamming if you use more tilts...
Once again: Good luck
