Sorry I can't protect this...
...yet.
You call it an episode, but really its like an alpha, which, in my opinion, is where it belongs.
+The art is OK, although you could improve it with more use of shading
+the voices were Ok, although 'that diamond' and 'the' art gallery are hardly relistic detail.
+the animation was limited, but OK as far as it went.
+you call it The plot, it there wasn't much really- its not that the movie is that bad, it isn't, but you create such expectations with notes like that.
I would seriously make the first episode about introducing the characters more- who or what is COAD?
If you show us a bit more before hand to show who is who, maybe showing what the diamond is- eg an advert in the paper saying "the great StrawberryCLock diamond is on show in the Legendary Frog museum this week" or something, then put in a bit more action or chase after he gets the diamond I think I would more than pass it and look forward to seeing more of your work.
Good start, but not there yet.
Best Wishes,
