Mate that was so good! I seriously can't find any faults in that. You have obviously put a shitload of effort into it as you mentioned and it has really paid off.
Hope to see more stuff like it and the idea was quite original.
I WANNA BE AS GOOD AS YOU!! WAAAAAAA :'(
Aaaaanyway.... overall it was fucking awesome and the character design was sweet too... loved the way you filmed him being created.
Kudos to you.
