It looks really nice and the leaves are a nice touch. The one thing my eye is drawn to is the lettering. I feel like perhaps the outline might be a bit too thin. It kind of feels like it doesn't fit with the background art. I might be wrong about the outline, it might be something else. I'm usually the type that needs to try something and see it to know if it's right, but there is something about the lettering I feel could be improved.
I played briefly but in-browser games cause my internet to have issues but one suggestion I had for the dialogue is to make the entire thing print out on the click of a button so as to bypass the typewriter effect.
