Absolutely gorgeous artwork and shading! I agree on the visibility issues mentioned below, there's room for improvement without compromising on the beauty. Also the jazz music was a great fit for this game!
One thing I didn't like was the sense, that my choices don't get much of a follow-up: It didn't seem like delivering the package did anything beyond the immediate change in stats. Maybe I just haven't played long enough, but I was waiting for a moment where the previous choice would come back to haunt (or reward me).
Keep going, it looks and feels really good. With improvements to form a more complex story, it might become a great game!
