A few things
First of all, the graphics saved this flash considerably. But watch those clipping errors and transitions next time.
The flash was way to long, I really couldn't sit through it all. Next time split it up into episodes.
Recording wise you might want to get some better equipment. But that requires money so I understand if you can't.
Also, Ren never yelled at Stimpy in the parts that I saw. It just does seem like them if they are having a pleasant two way conversation.
Over all you have a lot of potential but ya need to work on a few things before you can really make the most of it.
