congrats on making your first vid! 8D now you won't ever be able to stop +_+ you're here forever.
i think the music tone really fit how the anime looks (haven't seen it so I can't say how well it fits the story D: ) the pacing definitely picked up as you got to faster parts of the song, which i feel new editors sometimes have trouble with. there were some crossfade transitions in action scenes that were a bit jarring, but overall its an excellent first step
I definitely trial and error, but talking to other editors is also very helpful (most of them don't bite...)
for tutorials this may be a good first place to look:
http://www.animemusicvideos.org/forum/v ... m.php?f=59 may not be the most active but there are a lot of very knowledgeable people who are willing to help.
also, you should upload your video to the org so more people can see it and rate it! (and so scary kireblue doesn't move this thread to the general discussion forum ;D)
