Yeah! it's finally going to become a series! I was around when you first made the original clock-hero flash, and I was disappointed when nothing seemed to come of it. I await the first episode/animation with great anticipation.
Aside from that, criticisms:
Animations: mouth-movement was already addressed by Muzz-Xandre, so I'll leave that as "already known"
Sound: sound was, overall, well done. Two problems of note though.
1) the initial "jump" sound (mid-air, not off-roof.) had some odd clicking.
2) The wooshing sound as the hero lands on the roof after previously mentioned jump sounded like it was distorted slightly, enough to catch my attention.
Character Design: this is a question more than a criticism. Is the main character's hoodie supposed to be two colors(hood/body)? It's just something that struck me as curious.
