There are a couple things I wasn't a fan of, but those are personal preference and not an issue with the overall quality of the animation, so they aren't included in this review.
Speaking of, the animation is quite well done, perhaps not Zone quality, normally wouldn't compare, but you did use a Zone character. Still, well done. I would have liked to see a little more...detail. Blushing, some sweat maybe.
Overall, in a sea of awful animations, this is definitely one of the greats in terms of quality. Keep it up.
