I really liked the artwork in this VN. The colors and the perspectives in the bar evoke a pleasant atmosphere. A bit like like redrawing photos made with an analogue camera at a tropical summer vacation you had years ago, leaving memories that are being shaped by more and more nostalgia as time goes by...
In less rambling words: pretty warm and organic style with particularly nice shadings. And some very adorable expressions. Especially with Orion, he is a real cutie!
