maybe if you want to redo the description parts, where you layout part of the screen for the description, camera movement, and such.
obviously it would depend on who are you demo-ing this to, are they new clients, people you have not worked with before, in that case it might be too rough.
if your not in a hurry, and need a little touch up, i could help.
I've been watching it.. and re-watching it.. I think I will wait and have all my storyboards re-drawn before I send this my intended audience. Clarity is key, and she's a bit fuzzy.
