Hey Adam, the content itself is great and the tips are bang on. However, I think you should proof read the article again. An article on 'Improving Your Writing' loses a lot of credibility when it has sentences like:
> The character, 'hotel' has does an action 'wanted'.
which should be:
> The character, 'hotel', has an action, 'wanted'.
It also seems like you rely on a single source, Williams and Colomb (1990). Is this your personal summary of that book? Do you recommend reading it, or do you believe your post captures the most important points?
