Let me say this first: this community is about anime music videos (hence the name), so the two game videos aren't really what we do here. For the one anime video, you used Dragonball Z, so be prepared for the onslaught of criticism for that alone. The reason being is that DBZ is overused, and most people are tired of "Yet Another DBZ Action Video". Just wanted to give you fair warning. I'm going to be perfectly honest, but if you have any kind of ego whatsoever, you need to check it at the door. People here will offer honest criticism, but for the most part they will NOT sugar-coat anything for you. Flaws will be pointed out, ripped open, and mercilessly hounded upon. Take this criticism to heart, but don't see it as a personal attack. Too many times, we get people who want a critique, get told what's wrong, and they fly off the handle about how everyone is "elitist", or "out to get them" for some reason. If it seems that way, just remember we care about our hobby, and want the quality of the videos made to reflect that passion. So when you get criticism, pick through any ego-bruising and get to the meat of what the person is trying to say. Once you find that out, figure out how to incorporate that into your project.
As for advice on technique, source footage, and how to edit properly (i.e. using purchased DVD's and capable software), pleas read
HERE to gain an understanding of the basics.
All of that being said, the only way to truly improve is to keep editing, keep refining your technique, and never be afraid to try something new. Everyone had to start somewhere, and the surest way to stagnate is to give up when you see videos that seem almost impmossible to create.
