The art was okay in Harumi-chan for when it came out, but there are chunks of time where there's no background and they are just surround by a solid background color or gradient. The animation also isn't very smooth and suffers from some quality issues you see from this time.
Now the worst part of this hentai and what really killed its score was the sound, which I would have given a one but you can tell that some sort of quality was there before its release or dvd. The first thing I noticed that was awful was the sound effects, usually hentai aren't known for always having the best sound effects or at least natural sounding ones. However this one takes it to another level have poor quality, one that stood out right away was when the girls is masturbating at the beginning it sounds like someone making sounds with their mouth and not a girl playing with herself, which was kind of off putting. Then throughout the episode there is sound clipping, static, and cut outs in the audio that just make it frustrating to watch.
Overall I wanted to enjoy it more since the story and sex scenes were fairly solid, but the audio and lazy background art really hurt it. Which leaves me unable to recommend it to anyone to watch, unless you want to see what bad audio looks/sounds like in a hentai.
