Um... HORRIBLE
Most likely one of the worst movies I have ever seen on Newgrounds. I know nothing of Runescape until I read the author's plea to not judge his movie on it. Well I didn't, and the movie really sucked. Copy/paste normal fantasy storyboard, horrible voiceovers, choppy animations, cheezy backgrounds and speech. Must I say more? Flashing the screen during battle does not make it dramatic, it just means you lack the skills to make it better. I would make some revisions and work on your storyboard a little more. The cheezy one liner quotes from every single fanstay movie ruined most of this movie for me. Be creative and make yourself stand out. Work on your scene transitions alot more as well. And remember, just because it is easy to draw a straight line doesn't mean you should. Look around you, most of the world is not perfectly symmetrical. This will make viewers not pay attention to the quality of the graphics and attempt to pay attention to your story ( / constructive criticism).
In conclusion, If I were you, make this one of those links you just pass by, don't waste your time. Maybe if the author makes some improvements and revamps the storyline/dialogue more it will eventually be worthwhile. Have a good day =)
