I like this! the animation and the lip sync is pretty well done!
just a few things i'd like to point out.
be careful with continuity, at 8:20 the sorceress has no pubes.
at some points the characters make no sound, the Golem walking at 3:50 for instance, or the sex scene at 5:50, it would've been nice to have some discreet sound of the sex. the previous episode was a little better in this aspect. also the Golem has no gauntlets anymore!
maybe i'm being nitpicky, but the tattoos are not doing do the characters any good either, i can appreciate that the Golem has runes and the beast has tribals, but it would be better to have few well placed, meaningful tattoos than have several scattered around the characters. the japanese tattoo is just plain random.
LOL what am i doing with my life, reviewing the design in a CG porn movie.
anyways, i like this, but i think it would be easy to make it better, good luck!
