I really like the change in character visuals for the Eiyutan release. Going for a softer look and more detailed cg in general. Some characters almost look like a different person with the same hair color and clothes though. I wonder how this "new" Ren's angry expression looks like hehe. Doki*doki!

Koihime has a good story with memorable characters and a decent soundtrack. The only flaw was the artwork which I felt was too rugged and simple (lack of detail).
