I like this, it simply and clearly shows the stark difference in mediums, I would add though from a manipulation view that maybe the book state could have been enhanced with something imaginary rising out from it , butterflies , just something whimsical to add a bit more to the story of the image.
Overall a very nice image and I think it gets the message across nicely.
Thanks. Yes adding something coming out from the book would have been a plus but I don't know why I didn't think about it when I done it.
