An enjoyable read for sure but two things which I feel compelled to mention, first and foremost the image of the character Gandalf caused me to immediately feel like I was about to read some infantile drivel from some nerdy fantasy geek and secondly all of the 'bold' text kept forcing my attention away from the context of the message.
Please forgive my saying that about the Gandalf image for I do not consider you to be childlike in any way shape or form but that is the effect that image had on me, I just can't take people seriously when I see that sort of imagery. The over use of the bold text suggests that the writer is not aware that the reader is fully capable of understanding the importance of given words, your audience doesn't need to have their hands held whilst reading my friend, I would get shot of the bold text.
