I want to implement more features; I'm taking it step by step—some more social and others more focused on the game mechanics themselves. We'll see how it goes; little by little, I'll be creating more visuals to make it look better and more visually appealing.
Are you trying for AAA 3d graphics? Photorealism? XD I think the only one way you could make it visually "better" at this stage is to reticulate some splines so we could design a whole ass grove/garden and that sounds like way too much work.
Actually, something more along the lines of pixels or anime-style drawings, or the kind of art you see in some RPG games—I don't want anything 3D or anything like that; it's more for that hand-drawn style.
Oh in which case I think you've pretty much nailed it so don't obsess too much about it? :D
