Well honestly, its pixel sprite artwork - How close do you want them to look like a full-in-depth CG when its literally only a few pixels on the screen? That the game even have pixel sprite artwork is just amazing, since 9/10 RPGmaker games just leave that part out - only the top tier games have it. That said I think they look pretty much like the characters they portray.
- Not to mention, this dev. do everything himself. CG art, animation, pixel sprite artwork, coding, dialogue and story.
- Henteria Chronicles outsource the sprite artwork, so the dev. have more time for story and dialogue, making the quality really high from an artist who probably only do sprite artwork all day long. Not to mention his sprite artwork "is his scenes" so they need to be damn good
