Not a preview, just unfinished
It's a shame that you put this up a mere 4 hours after sweet_kat22 put his Batman preview flash up, because it's comparatively much worse. I've said this many times before, but I'll throw it out there one more time:
If you want to do a preview for an upcoming work, make a trailer. Just like movies do. Just like sweet_kat22 did with his. Honestly, Matt Greenwood's art style is better, IMHO, and I prefer the Danny Elfman cinematic score to the Hoobastank song in sweet_kat's flash. But I'm scoring this one lower because it ends abruptly, and isn't a true preview.
