Hey man!
First of all I enjoyed the anymation a whole lot. The story was fun and I liked how the boy seemed very sure of himself, keep the good work up, definately would want too see more of you. Though the setting confused me rather much. The music and the backgrounds reminded me of Asian influences, most likely Japan, yet the characters and the castle were more European style, now this is all fine if that was your intention, it was just a bit odd.
And why you get 4 stars instead of 5 is because the animation could have been a bit more fluent and polished, plus the music really did not work that well. The drums through the rest of the soundtrack constantly made me wonder if I was having two tabs open or some other music playing, so I hope you might find a way to make it more one soundtrack.
But in any case, keep the good work up!
Love to see more of this guy!
