I think the intro explaining what a reflective practitioner is defined as, is a great way to begin your post.
Maybe in the following paragraph you could highlight the reflecting methods you have used so far, or intend to use later (e.g. this blog, twitter etc.).
The example of your pitch combined with your thorough use of literature really gives your blog some depth and makes it interesting and informative.
You could also make the last few paragraphs more concise, focusing on the important details as I got a bit lost as it jumped around from ideas.
Overall an interesting post, backed up by lots of outside resources to help get your point across! :)
