I like the look! I really liked the wallpaper. The room had a very grand feeling because there is no visible ceiling. Almost like it stretches high above the players view.
One small suggestion would be to darken the blue in the eyes of the two characters on the right. Stu first I thought they were supposed to look creepy or something but then I zoomed in and saw that they had whites in their eyes also. I think the blue and the white are to close together to tell them apart.
Might just be my phones screen size though!
