You're pretty good at getting around projectiles. You have nice DJC angles ^.^
I also noticed that you're good about getting the kill when you need it. You also punished up-b's well.
Dair has a lot of lag even if you l-cancel it. You might want to try out SH autocancelled dairs. If you SH and dair asap, the dair will cancel itself in the air and you'll land lagless. It's a pretty good way to take advantage of dair's good combo potential without as many risks.
I noticed that, other than occasionally getting Link off the stage, you didn't really accomplish much from grabs. Grabs are hard to land with Ness, so you always want to make the most of them. Dthrow is good for setting up tech chases. Especially near the edge of the stage, where his tech options are limited, dthrow is a good choice. Fthrow can put him off the stage, but Ness isn't good at gimping, so you probably won't get much out of it. Uthrow can sometimes pseudo combo into uair. Even if it doesn't, you can "air chase" him. Figure out where he's going to land and grab him again. If he tries to land with a dair, punish with a wavedash back -> charged fsmash.
It's really important that you think things out and capitalize on mistakes to the max with Ness.
That's all. Keep up the awesomeness.
