Good and nice project. I have a few comments (that you can ignore if you write for your own satisfaction, or for your friends are relatives). Blogging is a very personal thing; I write this only because you asked for comments.
* There are hundreds of webpages, blogs, twitter and facebook accounts about the Camino. Try that your blog be original, unique and personal.
* Title. It is important, because many times it is the reason why readers click it (or not) when they are looking for Camino stuff. Yours is right, but descriptive. Would you be really interested in a blog with a title as "Felipe's trekkings"?
Try to be imaginative, as in "A million steps"; oriented to a particular audience ("My spiritual journey") or cool ("Been there, done that: My Camino"). Just some and probably silly examples...
* Authorship. Readers like to know who is the person behind the writing. I am not saying that you disclose your full name or personal address, but something as "I am a...I worked all my life in...always dreamed about...finally..." would be good.
Include in your profile a photo, if not of yourself, about something or some place or moment that represents you.
* Contents: You reproduced the text about the Botafumeiro from the cathedral webpage, including correctly the source. Try to put it in your own words (besides being more interesting this way, it happens that when Google detects your content is not original, it sends your blog down in the list of thematic searches). Even better, write about your personal experience ("I went to the cathedral...it was...I felt...).
* Upon your photos I suppose that you have already done the Frances (this is an info that could be added in "About") and probably the Primitivo. Well, write about your experiences in every stage, people you met, problems you had, albergues you liked, food, feelings, etc.
* I recommend that you put a lateral icon (a "widget") with a "Creative commons" kind of license, to protect your contents (they are free to use). Also, put an inconspicuous digital watermark in your photos...unless you don't mind if they start appearing in other webpages, without credit.
A caveat: blogging could be quite addictive. You can start your blog just as a vacation project, but after a while it can become an important (and time consuming) part of your life. But it gives some satisfactions, too...
Buen camino!
and good blogging!
