"thanks for taking the time to write such an indepth critique"

Don't mention it

"as for the sound I'm not too bad with sound effects, do you know where to get free/cheap sound effects?"

If you want really cheap ones i suggest you buy a microphone and a trial version of pro tools or some other soundediting program.
With this you can make your one sound and aren't limited by the contents of a cd..But if you really want a cd i would just google it

Good luck to you

Btw there are a couple of things you can change that don't cost a lot of time and will still make it look better
