I enjoyed the animation, but maybe you can do a little more frame by frame to smooth it out? The legs in the beginning felt awkward, because their motions were a little stiff and robot-like. I feel like framing that out may have been beneficial instead of what you have in there now (I'm going to go out on a limb and assume you just tweened it?) The other parts seem alright, but that close up on the legs is right in the beginning and really caught my eye before I got into the animation.
The art style is pretty well constructed, and I think it turned out pretty solid. The backgrounds are simple enough, but well designed. I think that helps with the still frame images a lot, and is probably the strongest part of the piece. The animation may be simple and repetitive and have a few minor problems, but the designs are solid, and I think that may in part be because the original was mostly design with limited animation. Either way, your choices for backgrounds and foregrounds, as well as the character designs and styles, worked out very well.
I'm also not upset about it being repetitive at all, I've seen the source material I get what you wanted to do with your parody. Not too concerned with the choice to make it so sexual either, there was plenty going on besides that.
Grats on your first front page, I'm watching out for new stuff from you.
