Great
I thought it was great, sure there's some parts where it is slightly let down, but overall you're making a full episode and attempting a lot more than what a lot of other NG uploaders attempt, so you have to get immediate props for that.
I think the animation and the art style is great. Individually, it's fairly standard, but when you realise you've kept that level of quality across the entire episode which is fairly long, then it becomes quite impressive.
Some places were hard to follow, inbetween scenes would have helped. Also although what audio you had was good, the continuity across scenes, various levels, and synchronisation need work and contributed towards it being hard to follow in places.
Also, one thing that slightly dissapointed me was the rather cliche characters and story. I'd like to see it branch away from that but understand how difficult that can be, especially now you've already set it in stone with previous episodes.
If I could, I'd give you an 8.5, but seeing as I can't I have to give an 8 seeing as the things listed above means it can't quite get a 9.
