No offence, but it was about time!
I've been waiting for this particular episode for a while now. At least it explains several recent events in the IMP (I do follow the stories behind the cartoons).
However, it contains some anachronisms. I'm not sure if this cartoon was made that way purposely, but I knew (from looking at HB's art) that the idea of lil' Brany existed a long time before this cartoon.
Also, I question your adding new characters into the cartoons. You haven't really added any new characters over the past episodes, and when I saw this for the first time, I felt disoriented because the beginning was nothing but new characters.
I have grown accustomed to your style of drawing, which is why I don't criticise the graphics as much as other people. The voices (and their subtitles) were hard to understand at times; I understand, however, that this was done necessarily to keep the Flash within filesize limits. The violence, which is present in nearly every IMP cartoon, gives it a nice touch of humour when in the right places. The other humour, however, lied in the fact that Bustin and HB are such pervs and the corny fight scenes between those two new characters. (By the way, will they appear in any subsequent episodes?)
My attitude towards your Flash creations have changed over time. I strongly encourage you to keep making these, and I anticipate your next creation.
[Note to self: this is the longest review I've given to any NG material!]
