.:Look Up The Walkthrough:.

Hello and welcome to the thing I have never done before! Okay, so, let's start!
Midori's confusion towards the puzzle she can't is seen very much, good job on that!
Ayano looking at the iPad simulates her with confusion of seeing what's the answer to that puzzle game they're playing. Oka seems to be bored, she's just waiting for them to get back on track. The room looks very realistic, is it a stage or just an image?
The models are very high quality, just Midori's hair could use a little.
In all, this is amazing work and I can't wait too see what else you have!
