1) First Page - if you want to be taken seriously loose the banners.
2) Typography - the font reminds me of something that you might see in a Simpsons halloween special.
3) The pentagram logo will put off a lot of potential clients. I would advise revising that because of the bad connectations.
4) The generic swish animation doesnt do it for me.
5) The transition of the logo to section isnt bad, but the sound has to go , or at least have a sound off button
I hope this helps you.
Never underestimate the power of stupid people in large groups
