If you haven't seen it yet, check out the document i added to the brief area with competative logos. You can see how much others stand out and how important it is to be simple and refined. There are a few things we can consider to be more dominant on the page: Using bolder type, Puting some type of border around the logo (like a box, oval or some form of background). I'll try to make more comments later.
i did this document before your entry was around, but yours is not bad.
