Bah, you guys are such hard ***** when it is unnecessary.
Anyway. You've been warned by the locals here. From now on, just make sure to throw videos in for critiquing in the specified thread. As for your videos, you did less than adequate, and odds are the opponents you faught (particularly the Meta Knight) were either taking it easy on you or were simply bad players. I'd point you to a guide for pointers, but the most generalized guide is mine, and I won't direct you there until I update it. If you want some visual aid on how to get better, watching videos of Neo, Roy_R, and Pierce here are good places to start. For reading material, you can pick up little tips here and there through some threads hanging around the front page, or go to Junks sticky up at the top.
