The storyline is brutal...
You've improved in Flash since the last iteration, but it doesn't seem like you've learned much about presentation. The character designs are nice, and the voice acting is solid. But the graphics still look so rough and jagged and not in a stylish way, because there's holes in the characters in a lot of places to where you can see the background, and white spots in the background where there wasn't enough cleanup. However, things like that can be forgiven for good storytelling, and here's what turns me off.
This cartoon accomplishes nothing. It talks in cryptics and has a bunch of shit thrown in that's impossible to understand for anybody except you who created it (not because it's the first Episode, that was my favorite excuse when I first started out). YOU as the artist were impatient with the storytelling and didn't take your audience into consideration when you made it. I can see your main priority with this flash was showing off all the characters and fires and fights and mystic conversations about killing sages and disappearing boys whose girlfriends cry.
When you make any flash, regardless of whether it's the first in a series or not, don't confuse your audience, you want to accomplish something story-wise so your audience walks away with some knowledge about what's going on and MAYBE a question or two, instead of "Hey that was kinda cool but what the hell was going on." It'll make things easier on you later on if you be more mindful of this, and easier on the audience. Now you have to work double-time to answer all the questions you created with this flash in later episodes, don't add anymore mysteries, please... Whether it's the first episode or not, that's no excuse for inconsiderate writing.
No hard feelings I hope Sci-fi, just being honest. I look forward to more of your work, I know you're still just getting your feet wet with flash.
