I have learned pretty much all by myself(sure there has been people giving me good tips). Actually just watching other lfs videos have teached me a lot things and different kind of tutorials helped me learning to use editing softwares (also Making LFS movies #2 thread was really helpful when I started making lfs vids).
Dont forget FireMike or Lynce! They are much more talented in LFS vids than me
I mean AE is wayyyy more complicated. If OP cant make better videos than that with vegas, he cant do it with AE. OP doesnt even use the full capacity of vegas.
And AE is actually just for effects. I recommend to do cutting in premiere or vegas. And IMO effects arent that important in lfs videos. Only a color correction, good cutting and good camera work is enough to produce great lfs vids.
Camera work is still poor, dont over do that blue color around that text, dont use swirls like that, color correction/gradient map is way too blue.
EDIT: I recommend to watch lfs videos from makers like Lynce, unokevaFB, firemike, squidhead, me (lol self promotion) etc. I mean I have learned A LOT from watching lfs videos from experienced makers.
