pretty darn good
i usually don't give good reviews, generally because if a movie ends up on front page there will be so many meaningless 10 out of 10s that it seems kind of pointless to jump in, that could indeed be the reason i feel compelled to resist giving you a straight-up 10/10.
however i genuinely liked your movie, even enough to have a look at your first one.
are you in any way influenced by CCC? it has that kind of light-hearted feel to it.
anyway, i liked the style, the animation, the song you chose (much better IMO then she-spider but that is a matter of taste) the design of the mountain king and the over all atmosphere of the whole thing.
comparing it to she-spider, i don't need to tell you your animation has become much more sophisticated, and there definitely seems to be a lot more care put into the crafting of this piece.
that is not to say, that she-spider is not also a very good piece, just in different ways, I'd say it was less atmospheric, more brick-to-face action, with a love story after taste.
why a 7? i feel a 7 is appropriate. one thing she-spider had over this, was substance. the artwork was more crude but you had much more going on, even if it all lacked explanation. but i think i understand what you're trying to say about the mountain king so i suppose an explanation is unnecessary.
if this movie is a strictly visual piece, then it is a success in being very visually pleasing. but if you are trying to tell me something about your character, then i would say more would be nice.
all in all i enjoyed this very much and if you do make another in the series i will make a point of watching it.
